ProCool Performance Lightweight: The Complete Guide to Wazoodle's Ultra-Light Wicking Fabric

What ProCool Performance Lightweight Is and Why It Matters

ProCool Performance Lightweight is AKAS Tex's ultra-light moisture-wicking fabric family — the lightest construction in the entire ProCool line. At just 65 GSM with 0.011–0.013" thickness, this single-knit jersey creates a barely perceptible wearing weight while delivering Foundation Wicking Technology for reliable moisture transport and accelerated evaporation. In independent AATCC 197 vertical wicking testing, Foundation Wicking construction transports moisture 0.6 inches in 30 minutes — the baseline performance tier that anchors the ProCool line.

With 40% crosswise stretch and 15% lengthwise stretch, Performance Lightweight provides more movement accommodation than any other ProCool construction. The 5-variant family spans three treatment types (Standard, Silver antimicrobial, Hydrophobic water-resistant) and two fiber sources (virgin and REPREVE recycled polyester), all manufactured in the USA, CPSIA certified, and Forever Chemicals-Free (no PFAS, BPA, phthalates). UPF 15–20 across all variants.

Performance Lightweight serves applications where minimal fabric presence is critical — athletic tops, running singlets, cycling jerseys, garment linings, professional clothing for hot climates, and specialized medical and industrial workwear. Customers consistently describe garments made from this family as so light they "hardly realize" they're wearing them.

The Complete ProCool Performance Lightweight Lineup: Standard, Silver, Hydrophobic, and REPREVE

All Performance Lightweight variants share 65 GSM weight, verified wicking per independent AATCC testing, 40% × 15% stretch, and Made in USA / CPSIA / Forever Chemicals-Free manufacturing. Variants differ by treatment and fiber source.

Virgin Polyester Series — 0.011" Thickness (3 Variants)
  • W-617 — ProCool Performance Lightweight: 60–63" width. The baseline ultra-light ProCool — Foundation Wicking without additional treatments. The most versatile entry point for athletic wear, garment linings, and casual clothing where moisture management and minimal weight matter most.
  • W-636 — ProCool Performance Lightweight Silver: 60–63" width with Silver Plus antimicrobial (99.9% bacterial inhibition through 50+ wash cycles). Customer-validated for professional clothing in tropical climates — users in the Bahamas report it maintains a polished appearance without overheating. Also validated for welding caps, bee suits, and medical uniforms.
  • W-563 — ProCool Performance Lightweight Hydrophobic: 60–63" width with HydroSHIELD water-resistant finish. Dual-function: wicks moisture away from skin on the inside while causing water to bead and roll off the outer surface. Customer-validated for ostomy pouch shields and multi-layer mask construction. The only ProCool variant with integrated water resistance.
REPREVE Recycled Series — 0.013" Thickness (2 Variants)
Key Concept — Lightweight Knit vs. Interlock Construction: ProCool Performance Lightweight uses single-knit jersey construction — thinner (0.011–0.013"), stretchier (40% crosswise), and lighter (65 GSM) than ProCool Performance Interlock's double-knit construction (0.016–0.027", up to 35% crosswise, 105–220 GSM). Lightweight edges may roll during handling unlike Interlock's flat-lying edges, but the ultra-light profile delivers barely perceptible fabric presence that Interlock cannot match. Choose Lightweight for athletic wear and linings where minimal weight is the priority. Choose Interlock for absorbent product liners and structured applications where stable edges and more body matter.

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

Choosing Your ProCool Performance Lightweight: Treatment and Fiber Guide

All Performance Lightweight variants share identical weight (65 GSM), stretch (40% × 15%), and wicking performance. Selection is driven entirely by which treatment adds the functionality your application requires.

Choosing Your Treatment
  • Standard (W-617) — Untreated baseline: Foundation Wicking at the best value. Choose when antimicrobial odor control, water resistance, or recycled content aren't required. Best starting point for athletic tops, garment linings, and custom casual wear.
  • Silver (W-636) — Antimicrobial odor control: Silver Plus inhibits 99.9% bacterial growth through 50+ wash cycles, extending freshness 2–4× between washes. Choose for extended-wear applications — professional clothing in hot climates, industrial workwear, athletic wear between washes. No bleach on Silver variants.
  • Hydrophobic (W-563) — External water resistance: HydroSHIELD finish causes water to bead and roll off the outer surface while wicking moisture from the skin side. Choose for medical barrier textiles (ostomy pouch shields), face mask outer layers, and athletic wear needing light splash resistance. Not a substitute for waterproof PUL in heavy-moisture applications.
Choosing Your Fiber Source
  • Virgin polyester (W-617, W-636, W-563) — 0.011" thickness: Slightly thinner profile than REPREVE variants. All three treatment types available (Standard, Silver, Hydrophobic).
  • REPREVE recycled polyester (W-292, W-291) — 0.013" thickness: 100% post-consumer recycled content diverting 5 plastic bottles per yard from landfills. Slightly thicker than virgin variants with identical wicking performance. Available in Standard and Silver treatments. Choose when sustainability documentation and recycled content credentials matter for product positioning.

Transparency note: All Performance Lightweight variants are somewhat see-through at 65 GSM, particularly in lighter colors. Plan for doubled layers, use as an underlayer beneath heavier fabric, or choose darker colors when opacity is required. This is an inherent characteristic of ultra-lightweight construction — not a defect.

Working With ProCool Performance Lightweight: Sewing and Construction Guide

ProCool Performance Lightweight requires more careful handling than ProCool Performance Interlock due to its ultra-light 65 GSM construction. The single-knit jersey structure is stretchier and less stable than interlock — edges may roll, and the fabric slides easily during cutting and sewing. However, multiple customers report successful projects with proper technique, and the fabric's stretch and softness reward the extra attention during construction.

Cutting and Layout
  • Fabric movement is the primary challenge: At 65 GSM, this fabric shifts and slides during cutting. Use pattern weights rather than pins, work on a grippy cutting mat, and use a rotary cutter with a fresh blade for clean edges.
  • Terial Magic stabilizer technique (customer-validated): Applying Terial Magic temporary stiffener before cutting and sewing controls the lightweight fabric during handling. The product washes out completely after construction — no residue. Particularly effective for the Hydrophobic variant (W-563).
  • Tissue paper backing: Place tissue paper under the fabric during cutting and sewing to prevent slippage and tunneling under the presser foot.
  • Stretch direction: 40% crosswise stretch is significantly greater than the 15% lengthwise stretch. Orient pattern pieces so the greater stretch wraps around the body for comfortable fit.
Sewing Recommendations
  • Needles: Ballpoint or stretch needles (70/10 or 80/12) prevent fiber damage and skipped stitches in the lightweight knit construction.
  • Walking foot recommended: Prevents fabric tunneling and shifting during sewing — especially important for Print variants and multi-layer construction.
  • Edge rolling: Unlike interlock, lightweight knit edges may roll during handling. Serge or overlock raw edges, or use stretch-stitch seams to secure edges and accommodate the 40% crosswise stretch.
  • Seam construction: Narrow zigzag or stretch stitch prevents seam popping under stress. Straight stitching alone may break during wear due to the fabric's stretch.
  • Thread: Polyester thread throughout for stretch compatibility and strength.

Pairing ProCool Performance Lightweight With Other Wazoodle Fabrics

ProCool Performance Lightweight functions primarily as a standalone garment fabric for athletic and casual wear, or as a moisture-wicking lining layer inside heavier garments. Unlike Performance Interlock, it is rarely used as the top layer in absorbent pad systems — the ultra-light construction lacks the body and edge stability preferred for that application.

Standalone Use — Athletic and Garment Applications
  • Primary use mode: Performance Lightweight works as a single-layer fabric for athletic tops, running singlets, cycling jerseys, shorts, and casual wear. Airflow at the outer surface enables evaporative wicking. Double-layer construction when opacity is needed.
As a Lining Layer Inside Other Garments
  • Moisture-wicking lining: At 0.011–0.013" thickness, Performance Lightweight adds wicking capability to outerwear, jackets, and structured garments without detectable bulk. The fabric's near-invisible profile makes it ideal for lining athletic jackets, costume pieces, and professional clothing.
  • Stripe and accent layer: Customers report using Performance Lightweight to add decorative performance stripes to existing garments, including commercially-made athletic polos.
Hydrophobic Variant (W-563) in Multi-Layer Systems
  • Face mask outer layer: Customer-validated as a two-layer outer shell in four-layer mask systems — paired with Zorb 3D for filtration and Dri-QWick Sports Mesh as the skin-contact inner layer.
  • Medical barrier layer: HydroSHIELD finish provides a breathable hydrophobic shield for ostomy pouch covers and medical textile applications where splash resistance matters without sacrificing comfort.

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

Common Applications for ProCool Performance Lightweight

ProCool Performance Lightweight's defining advantage is ultra-light fabric presence — at 65 GSM, it delivers wicking in a profile so minimal that wearers report barely noticing the fabric during activity. This characteristic drives application selection toward garments and products where weight and bulk must be minimized.

  • Athletic Tops, Singlets, and Jerseys — Running shirts, cycling jerseys, gym tops, and athletic shorts. The 2–3 hour complete drying time enables frequent washing in training schedules. Customers creating coordinating sportswear pieces report the fabric's appearance and performance work well as part of a mix-and-match athletic wardrobe. Tennis apparel specifically validated by customers.
  • Professional Clothing for Hot Climates — Customers in the Bahamas validate this fabric for professional attire that maintains a polished appearance without overheating during work hours in hot, humid conditions. The Silver variant (W-636) extends freshness between washes — critical when traveling or working in tropical environments.
  • Industrial and Protective Workwear — Customer-validated for welding caps (sweat-wicking in high-heat environments), bee suits (breathable coverage during outdoor hive work), and other protective workwear where moisture management under heat-generating conditions is essential. Silver treatment adds odor control during long work shifts.
  • Medical and Healthcare Applications — The Hydrophobic variant (W-563) is used for ostomy pouch shields, filling a market gap for soft, breathable hydrophobic barriers not readily available elsewhere. Silver variant validated for medical uniform construction. Multi-layer mask systems using Hydrophobic as the outer shell provide breathable protection.
  • Garment Linings — Adds moisture-wicking to outerwear, costume pieces, and structured garments without detectable weight. The 0.011" thickness disappears inside garment construction while adding wicking performance to any outer shell.
  • Intimate Apparel — Customers use Performance Lightweight for slips and incontinence panties where moisture-wicking and soft hand feel in direct skin contact are priorities. The ultra-light weight provides comfort without the bulk of heavier performance fabrics.
  • Casual Custom Clothing — Custom t-shirts for family members, personalized casual wear, and mix-and-match wardrobe pieces. Customers report the fabric meets expectations for everyday wear applications beyond just athletic use.
  • Costume and Fursuit Linings — Internal moisture-wicking layer for character costumes, fursuits, and performance wear where heat and perspiration management during extended wear is critical. Silver variants add odor control inside sealed costume environments.
  • Pet Apparel (Experimental) — Customers exploring performance fabric for dog clothing, using the moisture-wicking and lightweight properties for pet garments where breathability and comfort matter.

Use 1–2 layers depending on opacity and application requirements.

ProCool Performance Lightweight Care: Washing, Drying, and What to Avoid

ProCool Performance Lightweight's wicking performance is built into the fabric's engineered polyester fiber channels — the 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 ultra-light construction dries exceptionally fast — complete drying in 2–3 hours enables frequent washing during training schedules.

Washing

Wash at medium temperature with a zero-residue detergent free of softeners, fragrances, or oils. Extra rinse cycle recommended to prevent detergent buildup. Pre-washing is not required due to minimal shrinkage.

Drying

Dry on medium heat. Avoid high heat — polyester can glaze at sustained high temperatures. The 65 GSM construction dries rapidly even at lower heat settings.

What to Avoid

Never use fabric softeners or dryer sheets with any ProCool Performance Lightweight variant. These coat wicking channels and permanently destroy moisture transport. On Silver variants (W-636, W-291), softeners also eliminate antimicrobial effectiveness. On the Hydrophobic variant (W-563), softeners destroy both wicking and HydroSHIELD water resistance. No bleach on Silver variants (degrades antimicrobial treatment). Body oils, lotions, and detergent buildup also reduce wicking over time.

For why fabric softener damages performance fabrics, see Care Article 8 — Why Fabric Softener Destroys Performance Fabrics.
