ProSoft Organic Cotton Sherpa ECO-PUL: The Complete Guide to Wazoodle's Plush Organic Waterproof Fabric

What ProSoft Organic Cotton Sherpa ECO-PUL Is and Why It Matters

ProSoft Organic Cotton Sherpa ECO-PUL is a dual-function waterproof laminate that bonds 1 mil polyurethane film to organic cotton sherpa pile using ECO-Thermal Bonding Technology (permanent film fusion independently tested 50% stronger than competitor US-made PUL). At 285–350 GSM with a waterproof barrier rated at more than 100× any normal use pressure and breathability matched to resting body moisture output, this fabric provides a plush, absorbent sherpa surface on one side and a complete waterproof barrier on the reverse — the deepest pile texture in the ProSoft Organic Cotton ECO-PUL family.

The organic cotton sherpa base (82–90% organic cotton via US Cotton Trust Protocol) delivers a raised, textured pile that actively captures and holds moisture while providing soft grip on surfaces. ProSoft Organic Cotton Sherpa ECO-PUL features Waterproof 300X Technology (rated waterproof integrity through 300+ wash cycles) and SilentFlex Technology (quiet fabric-like drape). Customer reports consistently describe the fabric as soft, lightweight despite layered construction, and flexible in finished products. CPSIA certified, Forever Chemicals-Free (no PFAS, BPA, phthalates). Made in USA by AKAS Tex.

The Complete ProSoft Organic Cotton Sherpa ECO-PUL Lineup: Standard, Silver, Stretch-FIT, and FoodSAFE Variants

ProSoft Organic Cotton Sherpa ECO-PUL comes in four variants sharing the same sherpa pile + PUL construction principle, separated by antimicrobial treatment, stretch capability, and food-contact certification.

Outlier Note — W-532 Stretch-FIT: The Stretch-FIT variant diverges significantly from the other three sherpa variants. It adds Lycra for 4-way stretch (vs one-direction-only stretch in Standard/Silver/FoodSAFE), uses a different fiber blend (82/12/6 vs 85–90% cotton), runs narrower (48–50" vs 56"), heavier (350 vs 285–300 GSM), and thicker (0.065" vs 0.044"). Choose Stretch-FIT specifically when form-fitting applications require stretch and recovery — diaper covers that conform to body shape, fitted mattress protectors, or pet pad covers that wrap around cushions.

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

Choosing Your ProSoft Organic Cotton Sherpa ECO-PUL: Standard vs Silver vs Stretch-FIT vs FoodSAFE

ProSoft Organic Cotton Sherpa ECO-PUL's four variants all provide the same waterproof barrier with plush sherpa texture. Standard, Silver, and FoodSAFE share the same 56" width and 0.044" thickness — your choice among these three depends on antimicrobial or food-contact needs. Stretch-FIT is a distinct construction for form-fitting applications.

Working With ProSoft Organic Cotton Sherpa ECO-PUL: Sewing and Construction Guide

ProSoft Organic Cotton Sherpa ECO-PUL sews on standard domestic machines with the right setup. Customer reports emphasize easy cutting and sewing characteristics, quick project completion times, and compatibility with standard finishing techniques including bias binding and velcro closures. The fabric arrives cut-and-sew ready with no pre-washing required.

Pairing ProSoft Organic Cotton Sherpa ECO-PUL With Other Wazoodle Fabrics

ProSoft Organic Cotton Sherpa ECO-PUL's plush sherpa face absorbs while the PUL side blocks — and the raised pile creates a natural grip surface that prevents slippage in layered constructions. Pairing decisions focus on additional absorbent capacity or exterior finishing layers.

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

Common Applications for ProSoft Organic Cotton Sherpa ECO-PUL

ProSoft Organic Cotton Sherpa ECO-PUL serves as the combined absorbent-plus-waterproof layer in products where plush texture, surface grip, and leak protection are all needed. The sherpa pile provides the deepest, most textured surface in the ProSoft Organic Cotton ECO-PUL family — choose this when cushioned comfort and grip matter as much as waterproofing.

Pet bed covers and dog coats are the standout application for this family. Customers create removable, washable covers for memory foam dog beds where the waterproof barrier protects cushioning from accidents while sherpa provides comfortable sleeping surface. Makers have also constructed waterproof dog coats for larger breeds, finishing with bias binding and velcro closures — dogs wear the garments comfortably.

Castor oil pack therapy uses multiple variants across Standard (W-388) and Stretch-FIT (W-532). The sherpa-plus-PUL construction eliminates additional outer protective layers — absorbent sherpa contacts skin while PUL prevents oil leakage.

Period underwear and menstrual products use the Silver variant (W-521) and Stretch-FIT (W-532), both validated by customers for period underwear construction. Waterproof backing with absorbent sherpa face provides leak protection with comfort.

Cloth diaper covers provide a waterproof shell with plush sherpa interior against baby's skin. The Stretch-FIT variant (W-532) adds 4-way stretch for form-fitting diaper covers that conform to body movement.

Medical and therapeutic wraps use the Stretch-FIT variant (W-532) for specialized micro-current therapy wraps where waterproof protection with stretch and comfort is required for electrical therapy applications.

Reusable food storage uses the FoodSAFE variant (W-682) for food storage bags, bowl covers, and lunch bag linings with FDA-certified safety for all food types.

ProSoft Organic Cotton Sherpa ECO-PUL Care: Washing, Drying, and What to Avoid

ProSoft Organic Cotton Sherpa ECO-PUL maintains its Waterproof 300X Technology (300+ wash cycle durability) when care protocols protect the polyurethane film from chemical degradation and heat damage. The fabric arrives cut-and-sew ready — do not pre-wash before construction.

Washing

Wash in hot water (rated to 145–165°F) with a zero-residue liquid detergent — warm water extends film lifespan. Add an extra rinse cycle to remove detergent residues that accumulate on the polyurethane film.

Drying

Dry on medium heat only — never exceed 130°F (50°C). High heat causes polyurethane breakdown appearing as stiffening, cracking, or delamination.

What to Avoid

Manufacturing Odor

New fabric may have a noticeable smell from the thermal bonding process. This dissipates within 1–7 days of airing or after a single wash-dry cycle.

ProSoft Organic Cotton Sherpa ECO-PUL Specifications: Weight, Width, and Variant Comparison

ProSoft Organic Cotton Sherpa ECO-PUL's four variants share the same waterproof barrier and breathability but diverge in weight, width, thickness, and fiber content. W-532 Stretch-FIT is the most distinct — heavier, thicker, narrower, with Lycra for 4-way stretch.

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