ProCool TransWICK Supima Cotton Jersey Mesh: The Complete Guide to Wazoodle's Natural-Fiber Wicking Fabric

What ProCool TransWICK Supima Cotton Sports Jersey Mesh Is and Why It Matters

ProCool TransWICK Supima Cotton Sports Jersey Mesh is AKAS Tex's natural-fiber wicking jersey mesh — a 60% Supima cotton / 40% polyester blend that delivers TransWICK Technology one-way moisture transport with the soft hand feel and bio-based composition of premium American-grown cotton. In independent AATCC 195 Moisture Management Testing, TransWICK construction wicks moisture from skin to exterior in under 3 seconds, with the exterior surface absorbing at nearly 4× the rate of the skin side — keeping skin dry by moving moisture one direction and preventing it from returning.

This is the only TransWICK family built around a natural fiber majority. Supima cotton provides 45% greater tensile strength than conventional cotton (reducing pilling and fiber breakage), while the 40% polyester delivers the engineered wicking channels that create directional moisture transport. The TransWICK dual-fiber architecture uses hydrophobic fibers at the skin surface to push moisture away while hydrophilic fibers on the exterior pull moisture outward — creating one-way transport that prevents reverse migration back to the skin. In AATCC 197 vertical wicking testing, TransWICK fabrics transport moisture 5.5 inches in 30 minutes — more than twice the distance of any other ProCool construction.

At 175 GSM with 0.023" thickness, 30% × 5% stretch, and UPF 50+ sun protection (blocking 98% UV radiation), this family sits between the ultra-light TransWICK LITE (135 GSM) and the heavier Pique Mesh (300 GSM) in the ProCool range. With 3 variants spanning Standard, Silver antimicrobial, and FoodSAFE treatments, the Supima Cotton TransWICK serves period underwear, cloth diaper liners, athletic apparel, and food-contact applications. All variants are manufactured in the USA, CPSIA certified, Forever Chemicals-Free, and verified under the US Cotton Trust Protocol.

The Complete ProCool TransWICK Supima Cotton Sports Jersey Mesh Lineup

All Supima Cotton TransWICK variants share the same 60/40 Supima cotton/polyester blend, 175 GSM weight, 0.023" thickness, dual-sided jersey mesh construction (mesh side faces skin, smooth side faces exterior), verified moisture-wicking performance per independent AATCC testing, and UPF 50+. Variants differ by treatment.

TransWICK Supima Cotton Sports Jersey Mesh — 175 GSM / 0.023" Thickness (3 Variants)

W-602 — TransWICK Supima Cotton Sports Jersey Mesh: 58–60" width, 30% × 5% stretch. The untreated baseline — TransWICK one-way wicking with Supima cotton softness at the best value. UPF 50+. The most extensively customer-tested variant for period underwear: seven independent customers validated this fabric for menstrual and incontinence applications. Comparative testing against commercial period underwear brands (Bambody, Modibodi, Thinx) showed this fabric provides the driest surface feel after absorption — absorbs more slowly but maintains superior dry-feel comfort during extended wear. Also validated for children's summer activewear, nightgowns, and stay-dry sports bras.
W-634 — TransWICK Supima Cotton Sports Jersey Mesh Silver: Same construction with Silver Plus antimicrobial (99.9% bacterial inhibition through 50+ wash cycles). The dominant choice for commercial cloth diaper businesses — validated as a stay-dry liner that keeps babies dry and cool. Customers describe the hand feel as "lovely" and notably soft even among technical performance fabrics. Also validated for period yoga shorts and VR fitness headwear.
W-345 — ProCool FoodSAFE Supima Cotton: FDA food-contact certified (21 CFR 177.1680, 175.300) — validated safe for direct contact with food from −20°C to 250°F, including acidic foods, fatty foods, and extended storage durations. Customer-validated for adult disability care bibs, reusable food storage bags, baby bibs and burp cloths, and breast milk storage pouches.

Key Concept — Supima Cotton TransWICK vs Synthetic TransWICK: Both the Supima Cotton and Synthetic (poly/nylon) TransWICK families deliver one-way directional moisture transport — wicking moisture from skin to exterior in under 3 seconds with nearly 4× more absorption on the exterior than against skin (per independent AATCC 195 testing). The difference is fiber character. Supima Cotton TransWICK provides the soft, natural hand feel of premium cotton against the skin — choose it for applications where skin comfort matters most (period underwear, cloth diaper liners, baby products, intimate apparel). Synthetic TransWICK LITE offers lighter weight (135 GSM vs 175 GSM), slightly higher crosswise stretch, and nylon's abrasion resistance — choose it for athletic performance apparel, medical scrubs, and applications prioritizing durability and minimal weight over natural fiber softness.

All fabric specifications may vary ±10% due to textile industry manufacturing standards.

Choosing Your TransWICK Supima Cotton: Treatment Guide

All three variants share identical construction — selection is treatment-driven.

Choosing Your Treatment

Standard (W-602) — Untreated baseline: TransWICK one-way wicking performance with Supima cotton softness at the best value. Choose when antimicrobial treatment and food certification aren't needed. The most customer-validated option for period underwear — seven independent reviews confirm superior dry-feel performance.
Silver (W-634) — Antimicrobial odor control: Silver Plus inhibits 99.9% bacterial growth through 50+ wash cycles. Choose for cloth diaper stay-dry liners, period underwear, incontinence gussets, and athletic apparel where odor control between washings matters alongside Supima cotton comfort. The dominant choice in commercial cloth diaper manufacturing. No bleach on Silver variants; avoid high-heat drying (damages antimicrobial treatment).
FoodSAFE (W-345) — FDA food-contact certified: Validated safe for food contact at temperature extremes including acidic and fatty foods. Choose for reusable food storage bags, baby bibs and burp cloths, breast milk storage pouches, and adult disability care bibs where food-contact safety and wicking comfort are both required.

Absorption Speed Trade-Off: Customer comparative testing shows Supima Cotton TransWICK absorbs liquid more slowly than commercial alternatives — but provides the driest surface feel after absorption occurs. This makes it better suited for gradual flow (menstrual use, perspiration management) than sudden high-volume liquid events. On heavy menstrual flow days, the dry-feel benefit outweighs the slower absorption. On light-flow days in hot climates, heat retention during extended all-day wear can become noticeable.

Working With TransWICK Supima Cotton: Sewing and Construction Guide

TransWICK Supima Cotton handles well on standard sewing machines — customers describe it as sewing "without problems" and feeding smoothly through machines despite its technical performance features. The mesh side must face skin in finished products for directional wicking to function.

Cutting and Layout

Pattern weights over pins: Pin holes permanently enlarge mesh perforations. Use pattern weights and a rotary cutter for clean edges.
Mesh side marking: Identify the textured mesh side (skin contact / garment interior) and the smooth face side (exterior). Mark clearly before cutting — once pieces are separated, orientation can be confused in solid colors.
Bolt relaxation: Allow fabric to relax 30 minutes after unrolling before cutting — jersey mesh can stretch on the bolt during storage.
Pre-wash: Pre-wash to manage minimal shrinkage before cutting. Supima cotton content makes pre-washing more important than with fully synthetic ProCool fabrics.

Sewing Recommendations

Needles: Ballpoint or stretch needles (75/11 or 80/12) to prevent fiber damage in the jersey mesh structure.
Seam construction: Straight stitch or narrow zigzag for seams. For food storage items (W-345 FoodSAFE), minimize stitching holes that create potential leak points — topstitch or bind seam allowances.
Presser foot pressure: Reduce pressure to prevent stretching the 30% crosswise stretch during feeding.
Stretch compatibility warning: Avoid pairing Supima Cotton TransWICK with highly stretchy materials (spandex blends, elastics with high recovery) — the different stretch recovery rates cause unwanted wrinkling in finished products. Plan construction to minimize stretch-mismatch between layers.
Thread: Polyester thread for stretch compatibility and strength.
Laundering: Wash finished items in mesh laundry bags to prevent snagging on the open mesh structure.

Pairing TransWICK Supima Cotton With Other Wazoodle Fabrics

TransWICK Supima Cotton functions both as a standalone garment fabric and as a wicking layer in multi-layer absorbent systems — the dual-action capability (wicks moisture away AND holds fluid) makes it particularly effective in layered constructions.

As a Stay-Dry Layer in Absorbent Systems

Cloth diaper construction: Supima Cotton TransWICK Silver (W-634) as the skin-contact stay-dry liner, paired with bamboo sherpa and bamboo Zorb absorbent core layers. This specific combination is validated in commercial cloth diaper businesses — the TransWICK wicking keeps babies dry while bamboo layers handle absorption beneath.
Period underwear and menstrual pads: TransWICK as the skin-contact wicking layer, paired with Zorb absorbent core and ProSoft PUL waterproof backing. The one-way wicking with reverse migration prevention maintains dry-feel comfort during extended wear.
Incontinence gussets: Silver variant as the wicking layer in reusable incontinence underwear construction.

Standalone Use

Athletic and performance apparel: Single-layer construction for athletic tops, base layers, period yoga shorts, stay-dry sports bras, children's summer activewear, and temperature-regulating nightgowns. The 175 GSM weight provides sufficient coverage for standalone garments.
FoodSAFE applications: W-345 as a standalone food-contact layer for reusable food storage bags, baby bibs, adult disability care bibs, and breast milk storage pouches — optionally paired with ProSoft FoodSAFE PUL (W-396) for waterproof backing in food storage items.

Your results may vary based on product design, construction method, and end-use requirements.

Common Applications for TransWICK Supima Cotton

TransWICK Supima Cotton's defining advantages are the Supima cotton softness against skin, one-way wicking with reverse migration prevention for evaporative cooling, and dual-action capability (wicks AND holds fluid) — making it the preferred TransWICK fabric for skin-contact applications where natural fiber comfort matters alongside technical performance.

TransWICK Supima Cotton Care: Washing, Drying, and What to Avoid

TransWICK Supima Cotton's one-way wicking is built into the fabric's dual-surface fiber architecture and mesh construction — the directional moisture transport is a function of the physical structure, not a chemical surface treatment. Proper care protects the fiber channels that make the technology work. The Supima cotton component requires care attention that differs slightly from fully synthetic ProCool fabrics.

Washing

Wash at medium temperature with like colors using a zero-residue technical sports detergent. Extra rinse cycle recommended to prevent detergent buildup. Pre-washing recommended before cutting to manage minimal shrinkage — more important with this blend than with fully synthetic ProCool fabrics due to the Supima cotton content.

Drying

Dry on medium heat. Avoid high heat — excessive temperatures can damage the Silver Plus antimicrobial treatment on the W-634 variant and accelerate cotton fiber wear. Maximum ironing temperature 250°F with a press cloth if needed.

What to Avoid

Never use fabric softeners or dryer sheets with any TransWICK Supima Cotton variant. These coat wicking channels and permanently destroy the TransWICK one-way moisture transport and cooling performance. On the Silver variant (W-634), softeners also eliminate antimicrobial effectiveness. Body oils, lotions, and detergent buildup also reduce wicking over time. Supima cotton absorbs oils without PFAS treatment — this blend is more susceptible to oil-based wicking degradation than fully synthetic ProCool fabrics.
