Incontinence Underwear: Fabric Selection Guide — Building Reusable Protective Underwear for Adults

Incontinence Underwear: What It Is and What You Need to Build It

Reusable incontinence underwear is a washable, wearable protective garment that integrates absorbent and waterproof layers directly into the underwear construction — replacing disposable adult diapers and eliminating the need for separate pads or liners.

Home sewers, adaptive clothing makers, and small-batch manufacturers build these garments using two interconnected systems: a multi-layer absorbent gusset and a stretch garment shell that together create a single product that looks and feels like regular underwear while providing reliable bladder leak protection.

Every pair of reusable incontinence underwear combines two systems into one garment:

Absorbent gusset system — a layered panel extending from the front waistband to the back waistband, built from three functional layers: a wicking topper that keeps skin feeling drier, an absorbent core that captures and stores urine, and a waterproof barrier that prevents leaks to clothing
Garment shell — stretch cotton jersey body panels with elastic at waist and leg openings, providing comfortable fit, secure containment, and a normal underwear appearance that preserves dignity during daily wear

Protection level scales with gusset construction. Light protection (backup for stress incontinence) uses a thinner core suited for small, unexpected leaks during activity. Moderate protection (daytime wear) builds a mid-weight core for multiple small releases across 6–8 hour wear periods. Heavy protection (overnight and extended wear) uses maximum core weight for large-volume releases during 8–12 hour periods.

Incontinence underwear shares its gusset architecture with period underwear but differs in critical ways: urine volumes per event are typically higher requiring faster intake speed, the extended gusset must cover a larger area front-to-back to accommodate leak positions during sitting and lying as well as standing, urine chemistry creates different odor management challenges making antimicrobial treatment particularly valuable, and garments are frequently laundered in hot water with sanitizers — demanding higher material durability than standard menstrual use.

Key Concept — Two Systems, One Garment: The absorbent gusset and the garment shell serve entirely different functions and require different fabric types. Gusset fabrics need wicking, absorption, and waterproofing. Shell fabrics need stretch, recovery, and comfort. This guide covers every fabric family available for both systems, with specific product recommendations by protection level and construction approach.

Simplified Gusset Construction: Zorb 4D CORE PUL fabrics combine absorbent core and waterproof barrier in a single layer. Paired with a wicking topper, this creates a complete two-layer gusset instead of the traditional three-layer build — the thinnest route to full protection with the least bulk under clothing. See Incontinence Underwear: All-in-One Gusset Fabrics below.

Incontinence Underwear Wicking Layer: Fabric Families for the Gusset Top

The wicking layer is the skin-contact surface inside the gusset, responsible for pulling moisture away from the body and transferring it into the absorbent core beneath. In incontinence underwear, this layer determines how dry the garment feels during extended wear — a well-chosen wicking fabric creates a noticeably drier surface feel compared to a basic cotton layer that holds moisture against the skin.

Wicking performance matters more in incontinence underwear than in most other absorbent products because of the extended wear periods involved. Where a pad might be changed every few hours, incontinence underwear is often worn for 8–12 hours or more as a primary undergarment throughout a full day or overnight. Directional wicking technology — which prevents absorbed moisture from migrating back toward skin — maintains comfort across these extended periods.

Silver Plus antimicrobial treatment is the default recommendation for incontinence underwear wicking fabrics. Urine creates different odor challenges than menstrual fluid, and antimicrobial treatment at the skin-contact layer provides the first line of defense during all-day wear. Customer feedback from incontinence users specifically confirms that Silver Plus-treated fabrics do not retain odor or bacteria even with repeated use.

ProCool TransWICK Supima Cotton Sports Jersey Mesh — 175 GSM / 0.023"

W-602 (Standard) and W-634 (Silver Plus antimicrobial): 60% Supima cotton / 40% polyester, 30% × 5% stretch. TransWICK Technology creates one-way moisture transport — the exterior surface absorbs at nearly 4× the rate of the skin side, preventing reverse migration. Supima cotton provides premium softness for sensitive-area contact during all-day wear. The most customer-validated wicking fabric across absorbent product applications — cotton feel combined with engineered directional wicking makes it the consistently preferred gusset topper. Mesh-textured side must face the skin for directional wicking to function. Silver Plus variant recommended as default for incontinence — antimicrobial treatment inhibits bacterial growth for odor control during extended wear.

ProCool TransWICK X-FIT Sports Jersey Mesh — 200 GSM / 0.028"

W-615 (Standard) and W-611 (Silver Plus antimicrobial): 45% polyester / 40% nylon / 15% Lycra delivering TransWICK one-way transport with four-way stretch and elastic recovery — 40% × 20% stretch, the highest in the TransWICK line. The Lycra content allows this fabric to stretch and recover with body movement, making it the best wicking option for the gusset of fitted underwear styles where the topper must move with the garment. The heaviest wicking option at 200 GSM — choose when body-conforming stretch matters more than minimum weight.

ProCool Dri-QWick Jersey Mesh — 150 GSM / 0.023"

W-434 (Standard) and W-433 (Silver Plus antimicrobial): 100% polyester with open-hole mesh construction for maximum airflow. Dri-QWick Technology channels moisture through the fabric with strong directional transport, moving liquid significantly faster than foundation-wicking fabrics. Textured mesh face contacts skin; smooth back faces the absorbent core. The lightest wicking option at 150 GSM with the most airflow — particularly valued for warm-climate incontinence use where breathability during extended wear reduces heat buildup. 25% × 10% stretch.

Fabric	Weight	Thickness	Stretch	Best For
W-434 Dri-QWick Jersey Mesh	150 GSM	0.023"	25% × 10%	Maximum breathability — open mesh for warm-climate wear
W-602 TransWICK Supima Cotton	175 GSM	0.023"	30% × 5%	Most validated — natural cotton softness with strongest directional wicking
W-615 TransWICK X-FIT	200 GSM	0.028"	40% × 20%	Body-conforming Lycra stretch — fitted underwear styles

All fabric specifications may vary ±10% due to textile industry manufacturing standards. Silver Plus antimicrobial variants recommended as default for all incontinence applications. Some makers note that even with stay-dry absorbent cores, an additional wicking topper layer improves surface comfort — customers report the smooth interlock surface of wicking fabrics feels noticeably more comfortable than textured dimple surfaces directly against skin.

Incontinence Underwear Absorbent Core: Fabric Families for the Gusset Interior

The absorbent core is the capacity layer inside the gusset, responsible for capturing, distributing, and storing urine throughout the wear period. Core fabric selection determines three things that matter most in incontinence underwear: how much protection the garment provides, how bulky it feels under clothing, and how quickly it dries between washes — making this the layer where fabric choice has the greatest impact on whether the finished garment gets worn daily or sits in a drawer.

Bulk management is the central challenge in incontinence underwear cores. Unlike a removable pad, the absorbent core is permanently sewn into the gusset — too much bulk makes the garment visible under clothing, defeating the dignity-preserving purpose. Engineered super-absorbent fabrics provide the highest capacity-to-thickness ratio, achieving in one or two layers what conventional absorbents require six or more layers to match.

Silver Plus antimicrobial treatment is the default recommendation for incontinence absorbent cores. Urine chemistry creates persistent odor that builds during extended wear, and antimicrobial treatment throughout the absorbent system — not just the topper — provides the most effective odor control. Customer feedback confirms Silver Plus-treated fabrics maintain odor-free performance without degradation over time.

Zorb 3D Stay Dry Dimple — Three Weight Tiers

LITE (320 GSM / 0.050"): W-228 Standard, W-227 Silver — thinnest Zorb 3D option for light-protection gussets with minimal bulk under clothing
Standard (460 GSM / 0.080"): W-229 Standard, W-226 Silver — balanced capacity and profile for moderate-protection daytime underwear
Heavy Duty (650 GSM / 0.110"): W-552 Standard, W-551 Silver — maximum capacity for heavy-protection and overnight underwear
Hydrophobic polyester stay-dry surfaces on both face and back — raised dimple peaks wick moisture away while valleys capture liquid into the absorbent core. Either side can contact skin with identical stay-dry performance. Standalone-capable — does not require enclosing between fabric layers before washing. Two layers of LITE replace approximately 6 layers flannel; two layers of Standard replace approximately 8 layers flannel; two layers of Heavy Duty replace approximately 12 layers flannel. The preferred gusset core for incontinence underwear where stay-dry performance and moderate bulk both matter. Fast-drying characteristics mean quicker laundry turnaround for the rotation of 6–8 garments most users maintain. Silver Plus variants are the default recommendation — antimicrobial odor control through 50+ washes is especially valued for extended-wear incontinence underwear.

Zorb 3D Bamboo Dimple — Three Weight Tiers

LITE (340 GSM / 0.050"): W-688 Standard, W-233 Silver
Standard (475 GSM / 0.075"): W-234 Standard, W-232 Silver — two layers replace approximately 8 layers flannel
Heavy Duty (625 GSM / 0.100"): W-497 Standard, W-496 Silver — two layers replace approximately 12 layers flannel
70% bamboo viscose / 30% organic cotton surfaces provide the softest skin feel in the Zorb 3D lineup, sandwiching the same super-absorbent core. Long-term makers consistently rate this family as an overall favorite for absorbent product construction — the combination of bamboo softness, rapid absorption, and three-dimensional moisture distribution makes it a standout. Standalone-capable. Expect 5–6% shrinkage both directions — significantly more than polyester Stay Dry variants. Walking foot required for all tiers.

Zorb Original — 235 GSM / 0.080"

W-202 (Standard) and W-201 (Silver Plus antimicrobial): The thinnest and most economical Zorb variant — two layers absorb 10× their weight in under 2 seconds and replace approximately 8 layers flannel. At a fraction of the thickness per layer of Zorb 3D, this is the lowest-bulk absorbent option for light-protection gussets. Must be enclosed between other fabric layers (wicking topper and waterproof barrier) — unfinished edges release fibers if exposed during washing. Customer feedback confirms that the standard weight provides enough structural integrity to help gussets maintain shape and positioning during wear, where thinner alternatives may lack body. Silver Plus variant recommended as default for incontinence.

Zorb 3D Organic Cotton Dimple — 550 GSM / 0.085"

W-231 (Standard) and W-230 (Silver Plus antimicrobial): Organic cotton stay-dry surfaces with the Zorb 3D absorbent core between them — the all-natural fiber option for makers serving customers who prioritize organic materials at the skin-contact layer. The heaviest Zorb 3D variant at 550 GSM with highest compression resistance, retaining loft and capacity under body pressure better than lighter variants. Two layers replace approximately 9 layers flannel. Some users report organic cotton surfaces feel slightly wetter than polyester stay-dry surfaces — pairing with a wicking topper addresses this. Silver Plus variant recommended as default for incontinence.

Protection Level by Layer Count: For traditional three-layer gusset construction (wicking topper + absorbent core + waterproof barrier):

Light protection (stress incontinence backup): 1 layer LITE-weight Zorb 3D Stay Dry or 1–2 layers Zorb Original — provides capacity for small, unexpected leaks during activity
Moderate protection (daytime wear): 1–2 layers Standard-weight Zorb 3D Stay Dry or Zorb 3D Bamboo, or 2–3 layers Zorb Original — manages multiple small releases across 6–8 hour wear
Heavy protection (overnight/extended): Zorb 4D all-in-one is a better path to heavy absorbency than stacking multiple separate layers — see All-in-One Gusset Fabrics below

Fabric	GSM Range	Thickness	Flannel Equiv. (2 layers)	Best For
Zorb Original	235	0.080"	≈ 8 layers	Thinnest option — light gussets, minimum bulk
Zorb 3D Stay Dry Dimple	320–650	0.050–0.110"	≈ 6–12 layers	Preferred core — stay-dry both sides, fast drying
Zorb 3D Bamboo Dimple	340–625	0.050–0.100"	≈ 6–12 layers	Softest feel — top-rated by long-term makers
Zorb 3D Organic Cotton	550	0.085"	≈ 9 layers	Natural fiber option — highest compression resistance

All Zorb variants absorb 10× their weight in under 2 seconds and soak up liquid 20× faster than conventional bamboo, cotton, or hemp knits. All variants are Ready-AbZORB processed for full absorption from first use without conditioning washes. Absorbency improves with each wash cycle rather than degrading — customers report consistent performance across years of use.

Incontinence Underwear Waterproof Barrier: Fabric Families for the Gusset Backing

The waterproof barrier is the outermost gusset layer, positioned between the absorbent core and the garment shell. This layer prevents any moisture from reaching outer clothing during sudden large-volume releases or extended wear — the non-negotiable safety layer that makes incontinence underwear functional.

Two properties matter most for waterproof barriers in underwear gussets: flexibility and silence. A rigid or crinkly barrier layer in a stretch garment creates noticeable noise during movement and resists the body-conforming fit that makes incontinence underwear feel like regular underwear. ProSoft ECO-PUL fabrics are specifically engineered for soft, noiseless waterproofing with the flexibility to move within a stretch garment.

No Fabric Softeners — Ever: Any fabric softener contact — liquid softener, dryer sheets, or detergents containing softener — coats the PUL membrane and permanently degrades waterproof performance. Use only softener-free detergents. This applies to every wash cycle for the life of the garment.

ProSoft 1 mil ECO-PUL — 155 GSM / 0.018"

W-375 (Standard) and W-274 (Silver Plus antimicrobial): 1 mil polyurethane laminate bonded to interlock jersey backing — the standard waterproof barrier with the widest color range. Withstands hydrostatic pressure over 100× normal use conditions while maintaining breathability — allows moisture vapor to escape while blocking liquid, reducing the bacterial growth environment from trapped humidity. 10% crosswise stretch accommodates gusset movement. The most commonly used PUL weight across all absorbent product construction — proven durability through hundreds of hot water wash cycles when cared for properly. Available in widest color selection for matching garment shell fabric.

ProSoft 2 mil ECO-PUL — 180 GSM / 0.022"

W-273 (Standard) and W-268 (Silver Plus antimicrobial): Heavy-duty alternative with a firmer body and less stretch (5% crosswise versus 10% for 1 mil). The additional barrier thickness provides extra waterproof margin suited for heavy-protection overnight underwear and institutional use where maximum barrier durability under aggressive wash conditions matters most. 5% crosswise stretch — slightly less flexible than 1 mil but still accommodates gusset movement within a stretch garment.

ProSoft Lightweight ECO-PUL — 100 GSM / 0.013"

W-579 (Standard): The thinnest available waterproof barrier at 100 GSM — 35% lighter than standard 1 mil PUL. Provides identical waterproof protection with minimal contribution to gusset bulk and maximum flexibility. Choose when compressed gusset thickness is the primary concern — this barrier adds the least possible waterproof weight to the layered system. Particularly valued in incontinence underwear where every fraction of thickness matters for discreet appearance under clothing. 10% crosswise stretch.

Fabric	Weight	Thickness	Stretch	Best For
W-579 ProSoft Lightweight ECO-PUL	100 GSM	0.013"	10% crosswise	Minimum bulk — thinnest waterproof layer possible
W-375 ProSoft 1 mil ECO-PUL	155 GSM	0.018"	10% crosswise	Standard barrier — widest colors, proven durability
W-273 ProSoft 2 mil ECO-PUL	180 GSM	0.022"	5% crosswise	Maximum durability — heavy-protection and institutional use

All ProSoft ECO-PUL fabrics withstand hydrostatic pressure over 100× normal use conditions and maintain waterproof integrity through hundreds of wash cycles when properly cared for (no fabric softener, no high-heat drying).

PUL has a learning curve but sews easily once techniques are understood — both standard sewing machines and sergers handle it well.

Incontinence Underwear All-in-One Gusset Fabrics

Zorb 4D CORE PUL fabrics combine a Zorb absorbent core with a waterproof PUL barrier bonded into a single layer — replacing the separate absorbent core and waterproof barrier with one fabric. Paired with a wicking topper, this creates a complete two-layer gusset instead of the traditional three-layer build.

For incontinence underwear, the all-in-one approach solves the bulk problem directly. Instead of stacking multiple absorbent layers plus a separate waterproof barrier — which can push compressed gusset thickness past the point of discreet appearance — a single Zorb 4D layer provides both functions at a fraction of the combined thickness.

The thinnest combination: Zorb 4D Stay Dry V2 (0.060") plus a wicking topper produces a complete gusset under 0.090" compressed — noticeably thinner than even a moderate three-layer build.

This is the recommended path to heavy protection. Rather than stacking three or four separate absorbent layers (which creates bulk, bunching, and drying challenges), Zorb 4D HD provides heavy-capacity absorption in a single layer that maintains consistent thickness across the gusset.

Pin-Free Construction Required: All Zorb 4D CORE PUL fabrics contain an integrated waterproof PUL membrane. Pins create permanent holes that compromise waterproofing. Use fabric clips, pattern weights, or adhesive tape for all handling and construction steps.

Zorb 4D Stay Dry CORE PUL V2 — 425–475 GSM / 0.060"

W-647 (Standard) and W-646 (Silver Plus antimicrobial): The thinnest all-in-one option — stay-dry dimple face with integrated Zorb absorbent core and PUL waterproof backing in a single layer at just 0.060" thickness. V2 construction represents the latest generation with improved bonding between layers. Paired with a wicking topper, this creates the slimmest possible complete gusset — the combination that comes closest to regular underwear thickness. Silver Plus variant recommended as default for incontinence.

Zorb 4D Stay Dry CORE PUL V1 — 450–500 GSM / 0.070"

W-526 (Standard) and W-540 (Silver Plus antimicrobial): The standard all-in-one with stay-dry dimple face, integrated Zorb core, and PUL waterproof backing. Slightly heavier than V2 at 0.070" thickness. Available in print options for visible gusset designs. Silver Plus variant recommended as default for incontinence.

Zorb 4D Stay Dry CORE PUL HD — 800–850 GSM / 0.115"

W-372 (Standard): The maximum-capacity all-in-one — heavy-duty Zorb absorbent core with PUL waterproof backing. At 800–850 GSM, this single layer provides heavy protection equivalent to multiple stacked Zorb 3D layers, but in a consistent thickness that resists the bunching and shifting problems of multi-layer builds. The recommended option for overnight incontinence underwear and heavy daytime protection — provides maximum capacity while maintaining the structural advantages of single-layer construction.

Zorb 4D Organic Cotton CORE PUL V1 — 650–700 GSM / 0.140"

W-492 (Standard): Organic cotton absorbent face with integrated Zorb core and PUL waterproof backing — the natural-fiber all-in-one option. The organic cotton face layer supports organic labeling claims for makers serving that market segment. At 650–700 GSM, this provides heavy absorbency from a single layer. Note that the PUL backing layer contains polyester — the organic cotton designation applies to the absorbent face material, not the complete fabric construction.

Incontinence Underwear Shell and Body Fabrics

The garment shell is everything outside the gusset — front panel, back panel, waistband, and leg openings. Shell fabric selection determines how the garment fits, feels, and appears under clothing. The shell must provide enough stretch and recovery to accommodate the compressed gusset panel while maintaining the appearance of regular underwear.

Shell fabrics require different properties than gusset fabrics. Where gusset layers need wicking, absorption, and waterproofing, the shell needs four-way stretch for comfortable body fit, elastic recovery to maintain shape through hundreds of wash cycles, soft hand for all-day skin contact, and enough structure to contain elastic at waist and leg openings without distortion.

ProECO Stretch-FIT Organic Cotton Jersey — Three Weight Tiers

LITE (135 GSM / 0.020"): W-411 Standard, W-556 Silver — 95% organic cotton / 5% Lycra, 40% × 25% four-way stretch. The lightest shell option for minimal-bulk underwear where discreet appearance under fitted clothing is the top priority. The high stretch ratio provides excellent body-conforming fit at minimal weight.
Standard (200 GSM / 0.030"): W-412 Standard, W-633 Silver — 95% organic cotton / 5% Lycra, 30% × 20% four-way stretch. The most commonly used shell weight for incontinence underwear — balanced combination of soft hand, structural integrity, and stretch recovery that maintains shape through hundreds of hot water wash cycles. Smooth jersey surface provides a comfortable, familiar feel against skin during all-day wear.
Heavy (300 GSM / 0.034"): W-568 Standard, W-598 Silver — 90% organic cotton / 10% Lycra, 35% × 35% four-way stretch. Maximum structure and recovery for underwear that must contain heavier gusset builds without distortion. The higher Lycra content provides the strongest elastic recovery in the line — particularly valued for overnight incontinence underwear where the garment must maintain secure positioning during sleep movement.
All tiers are manufactured by AKAS Tex in the USA. Organic cotton provides breathability and softness; the Lycra content provides the stretch recovery that prevents the garment from losing shape during extended wear and repeated laundering. Silver Plus antimicrobial variants available across all tiers for odor control during extended wear.

Fabric	Weight	Thickness	Stretch	Best For
W-411 Stretch-FIT OC Jersey LITE	135 GSM	0.020"	40% × 25%	Lightest shell — maximum discretion under fitted clothing
W-412 Stretch-FIT OC Jersey	200 GSM	0.030"	30% × 20%	Standard shell — balanced comfort, structure, and durability
W-568 Stretch-FIT Heavy OC Jersey	300 GSM	0.034"	35% × 35%	Maximum structure — heavy gussets, overnight wear

Select shell colors and styles that resemble regular underwear — briefs, bikini, or boyshort styles in standard underwear colors. The shell should not draw attention to the garment's protective function.

Elastic Components

Waist elastic (1–1.5" wide) and leg elastic (3/8–1/2" wide) create the secure containment that prevents leaks at garment openings.
Choose chlorine-resistant elastic rated for 200+ hot water wash cycles — standard lingerie elastic degrades rapidly under the aggressive laundering protocols incontinence garments require.
Fold-over elastic, plush elastic, and swimwear-grade elastic provide the durability and recovery needed for long-term incontinence use.

Incontinence Underwear Construction Essentials

Gusset Assembly Sequence

Build the gusset as a complete unit before attaching to the garment shell. Layer all gusset materials in correct sequence — wicking topper on top (skin side), absorbent core in the middle, waterproof barrier on the bottom (clothing side).
Use fabric clips extensively, then channel-stitch through all layers at 1–2" intervals to prevent absorbent shifting during wear and laundering. Never use pins — pin holes through PUL or Zorb 4D are permanent leak points.

Extended Gusset Coverage

Incontinence gussets require front-to-back waistband coverage — typically 8–12" wide and 14–18" long — significantly larger than period underwear gussets.
This extended coverage accommodates leak positions during sitting, lying, and standing without gaps at gusset edges.
Measure the wearer's actual front-to-back coverage needs rather than using standard underwear gusset dimensions.

Bulk Management at Seam Junctions

The point where the multi-layer gusset meets the single-layer shell creates a significant thickness transition.
Grade seam allowances (trim each layer to a different width) to distribute bulk gradually rather than creating a hard ridge.
Stagger quilting lines near edges to taper thickness toward gusset boundaries.

Pin-Free Techniques for Waterproof Layers

Use fabric clips, binder clips, or adhesive tape instead of pins for any construction step involving PUL or Zorb 4D fabrics. Pins create permanent holes that compromise waterproof integrity.
This applies to all handling — pattern layout, cutting, assembly, and fitting.

Elastic Application

Apply elastic at 0.7–0.8× stretch ratio — divide elastic and garment edge into quarters, match marks, and stretch elastic while sewing.
The garment fabric should not stretch when elastic is sewn at proper tension.
Use fold-over elastic with zigzag or 3-step zigzag stitch. Test fit before final elastic application to ensure waist and leg openings provide secure seal without uncomfortable binding during extended wear.

Incontinence Underwear Care

No Fabric Softeners — Ever: Any fabric softener contact — liquid softener, dryer sheets, or detergents containing softener — coats absorbent fibers reducing capacity and damages PUL waterproof coating. This damage is progressive and may be irreversible. Use only softener-free detergents for every wash cycle.

Wash and Dry Protocol

Pre-Rinse Protocol: Rinse soiled garments in cold water immediately after removal — this prevents urine from setting into fibers and reduces staining. Do not use hot water for pre-rinse as heat sets protein-based stains.
Wash Protocol: Machine wash with enzyme-based, softener-free detergent. Cold or warm water preserves PUL integrity longer than hot water, though hot water (up to 140°F) is acceptable when sanitizing is needed. Add oxygen bleach for sanitizing — never chlorine bleach, which degrades both absorbent fibers and PUL laminate.
Dry Protocol: Line dry or low heat tumble dry. High heat damages PUL waterproof coating. Zorb 3D Stay Dry variants dry fastest among all Zorb families — an advantage when maintaining a rotation of 6–8 garments for daily use.
Strip Wash (Periodic): Hot water + detergent + oxygen bleach with extra rinse cycles removes buildup that gradually reduces absorption. Strip wash when absorbency noticeably slows — frequency depends on detergent type and water hardness in your area.

Incontinence Underwear Certifications and Safety

Reusable incontinence underwear fabrics contact sensitive skin for extended wear periods — typically 8–12 hours for daytime use and longer for overnight protection — making safety certifications an important consideration when selecting materials for every layer of the gusset system and garment shell.
