NeoShell is a waterproof, air-permeable fabric technology developed by Polartec for performance shells. Its electrospun membrane is designed to let a small amount of air move through the laminate while resisting rain, helping high-output users release heat and moisture more continuously than they can in many low-air-permeability shells.
For brands and sourcing teams, the important point is that NeoShell is not one universal fabric specification. Polartec can pair the membrane with different woven or knitted face fabrics and backers, so weight, stretch, hand feel, abrasion resistance, water resistance, air permeability, color options, and price can vary by style. Evaluate the exact article, test method, garment construction, and destination-market requirements rather than relying only on the NeoShell name.

What Is NeoShell Fabric?
NeoShell is a proprietary Polartec technology that combines a porous waterproof membrane with textile face and backer layers. Polartec introduced the technology in 2011 and describes it as a bridge between a softshell and a conventional hardshell: waterproof protection with a softer, quieter hand, comfortable stretch in suitable constructions, and measurable air exchange.
The distinction between air permeability et moisture-vapor transmission matters. Air permeability measures air passing through a fabric under a specified pressure differential. Moisture-vapor tests measure water vapor moving through a material under a particular laboratory method. Both can inform comfort, but values from different methods or conditions are not directly interchangeable.
Polartec’s published overview gives NeoShell a 10,000 mm waterproof rating. This is a useful technology benchmark, not a substitute for a style-specific test report. Lamination conditions, face fabric, backer, seam construction, aging, contamination, and laundering can all affect the performance of a finished garment.
Propriétés clés
- Air-permeable waterproof protection: The membrane’s fibrous pore structure is designed to support continuous air exchange while blocking liquid water under its rated conditions.
- Soft and relatively quiet hand: Many NeoShell constructions are less crisp than traditional rigid hardshell laminates, although the face textile strongly affects the final feel and sound.
- Stretch options: Knit, mechanical-stretch, or elastomer-containing face constructions can improve mobility. The brand name alone does not guarantee four-way stretch.
- Low inherent insulation: NeoShell primarily manages weather protection. Thermal performance comes from the face, backer, garment design, and layers worn underneath.
- Style-dependent durability: Abrasion and snag resistance depend on the face yarn, fabric construction, weight, finish, and use area. High-wear zones may need a stronger face fabric or reinforcement.
- DWR-dependent surface behavior: The face commonly uses a durable water-repellent treatment to reduce surface wetting. DWR helps preserve comfort but is different from the membrane’s resistance to water penetration.
History and Current Position of NeoShell
Polartec launched Power Shield Pro in 2009 and introduced NeoShell in 2011 as a more waterproof, air-permeable weather-protection platform. The company later collaborated with brands on variations using different face and backer fabrics. A 2016 Teton Bros. project, for example, combined NeoShell with supple mechanical-stretch nylon and more abrasion-resistant nylon in different garment zones.
NeoShell has since appeared in jackets, pants, gloves, cycling garments, ski and snowboard shells, and limited footwear applications. It remains referenced in Polartec’s official technology stories and partner releases. However, Polartec’s current main weather-protection category page emphasizes AirCore, Power Shield Pro, Power Shield RPM, and Windbloc rather than listing NeoShell in its summary. Buyers should therefore confirm current NeoShell style availability, lead time, minimum order quantity, and support directly with Polartec or an authorized channel before building a collection around it.
How Is NeoShell Fabric Made?
The detailed recipe is proprietary, but the disclosed production concept has three main stages.
1. The Membrane Is Formed by Electrospinning
Electrospinning uses an electric field to draw a polymer solution into extremely fine fibers. These fibers collect as a thin, interconnected web with many small pores. In NeoShell, the resulting polyurethane-based membrane is engineered to balance resistance to liquid water with controlled movement of air and water vapor.
This is different from treating an ordinary woven fabric with a simple waterproof coating. The membrane is a separate functional layer whose pore structure contributes to the laminate’s performance.
2. The Membrane Is Laminated to Textile Layers
The membrane is bonded to a face fabric and, in many constructions, an inner backer. The face may be woven or knitted and can be engineered for stretch, abrasion resistance, weight, color, or hand feel. The backer protects the membrane from the wearer and other garment layers while influencing comfort, moisture movement, and snag resistance.
Polartec has stated that it can create NeoShell versions with different fabrics on either side of the membrane. This explains why two NeoShell articles can feel and perform differently even though they use the same branded membrane platform.
3. The Laminate Becomes a Finished Garment System
The finished laminate is cut and sewn by a garment manufacturer. Seam tape, thread, zippers, vents, pattern design, hood construction, pocket bags, and reinforcement panels all influence the result. A waterproof fabric does not automatically create a waterproof garment: seams and openings must be designed, sealed, and tested for the intended end use.
Brands considering stretch shell development can also review how face-fabric construction and tension control affect performance in FabricsTrades’ guide to the processus de fabrication de tissu extensible dans quatre directions.
How Is NeoShell Fabric Used?
NeoShell is most useful where the wearer needs weather protection and generates substantial body heat. Common applications include:
- Lightweight and midweight rain jackets
- Alpine, ski, and snowboard shells
- Cycling and trail-running jackets
- Waterproof or weather-protective pants and salopettes
- Gloves and selected footwear components
- Stretch shell panels in hybrid garments
For high-output sports, a more air-permeable laminate can reduce the need to wait for pressure and humidity to build before moisture moves outward. For prolonged exposure to extreme rain, heavy pack straps, kneeling, or sitting on wet surfaces, buyers should give greater weight to hydrostatic resistance, reinforcement, seam design, and post-aging performance.
The best material therefore depends on the use case. A light running shell, a mountaineering jacket, and a ski pant should not share the same acceptance specification merely because all three use NeoShell.
Avantages et limites
Main Advantages
- Combines waterproof protection with intentional air permeability
- Can deliver a softer, less rigid hand than many conventional hardshells
- Supports stretch and close-fitting garment designs when paired with the right face construction
- Can be engineered with different face and backer textiles for different performance briefs
- Suits high-output outdoor activities where heat and moisture management are priorities
Important Limitations
- A 10,000 mm benchmark is not the highest hydrostatic rating available in the shell market and may not fit every severe-weather brief.
- Air permeability, moisture-vapor transmission, and waterproofness can change by style and cannot be compared fairly without matching test methods and conditions.
- Surface wetting can still reduce comfort when the face DWR is dirty, abraded, or depleted.
- Stretch, weight, abrasion resistance, and recycled content are construction-specific, not universal NeoShell attributes.
- Seam tape compatibility and bonding conditions must be validated during garment development.
- Branded laminate availability, MOQ, color minimums, and lead times can limit small or fast-moving programs.
Where Is NeoShell Fabric Produced?
NeoShell was developed by Polartec in the United States. Polartec’s current manufacturing overview says its fabrics are formed in Hudson, New Hampshire, and finished at Polartec Tennessee Manufacturing in Cleveland, Tennessee. That company-level statement should not be converted into a blanket country-of-origin claim for every NeoShell style or shipment.
For customs, labeling, trade agreements, and brand claims, request the actual fabric declaration, invoice data, and country-of-origin documentation for the selected article. The location where a membrane is formed, a laminate is finished, a garment is cut and sewn, and a product obtains origin under a destination market’s rules can be different.
How Much Does NeoShell Fabric Cost?
There is no reliable universal per-meter price for NeoShell. Commercial quotes vary with:
- Polartec style number and construction
- Face and backer fiber composition
- Fabric weight, usable width, color, and finish
- Recycled or other specified content
- Order volume, color minimums, and sampling route
- Testing, inspection, documentation, and packaging requirements
- Incoterms, freight, duties, and currency
- Whether stock, development yardage, or a production run is required
Compare quotes on the same specification and commercial basis. A lower fabric price can be offset by higher minimums, more cutting loss, seam-tape problems, shade variation, failed tests, or delayed replenishment.
Are There Different Types of NeoShell?
NeoShell is a technology platform rather than a single fixed fabric. Polartec has engineered versions with different textile layers, including supple stretch constructions and more abrasion-resistant woven faces. It is more accurate to discuss style-specific NeoShell constructions than to treat “original” and “updated” NeoShell as standardized market grades.
Power Shield, Power Shield Pro, Power Shield RPM, Windbloc, and AirCore are related Polartec weather-protection technologies, not types of NeoShell. GORE-TEX, Columbia OutDry, The North Face FUTURELIGHT, and Outdoor Research AscentShell are external alternatives or branded systems. Each uses its own product architecture, test claims, commercial model, and intended applications, so comparisons should use matched finished-fabric data rather than brand-level generalizations.
How to Specify and Test NeoShell Fabric
A buyer-ready specification should identify the exact fabric and the performance needed after realistic use, not merely state “NeoShell or equivalent.” At minimum, request:
- Article identity: Polartec style number, layer construction, face and backer composition, nominal GSM, usable width, color, and finish.
- Résistance à l'eau : A current report using a named method such as ISO 811 for hydrostatic pressure, including units, conditioning, sample direction, and pass criteria.
- Air permeability: A report using a method such as ASTM D737, with the pressure differential and units stated.
- Moisture-vapor performance: The method, test conditions, orientation, and units. Do not compare values generated by different methods as if they were equivalent.
- Surface water repellency: Initial and after-care performance using an agreed method such as AATCC TM22 or ISO 4920.
- Durabilité: Abrasion, tear, tensile or burst strength, dimensional stability, colorfastness, delamination resistance, and any application-specific requirements.
- After-wash performance: Repeat critical waterproof, air-permeability, and surface-wetting tests after an agreed number of cycles using a defined procedure such as ISO 6330.
- Garment validation: Seam-tape adhesion, seam leakage, zipper and hood performance, mobility, noise, condensation comfort, and field wear.
- Chemical and market documents: Restricted-substance information, PFAS declaration or test evidence where required, safety data for relevant chemicals, certificates claimed for the exact article, and country-of-origin documents.
Use sealed approval samples and record test methods, tolerances, and sample conditioning in the purchase specification. FabricsTrades’ guide d'inspection de la qualité des tissus provides a broader framework for roll inspection and pre-shipment control.
Sustainability and Chemical Considerations
NeoShell commonly combines a polyurethane-based membrane with synthetic face and backer textiles. Its environmental profile therefore depends on raw-material source, fabric weight, recycled content, process chemistry, energy and water use, durability, care, manufacturing yield, and end-of-life route.
Polartec announced in 2021 that it had eliminated PFAS from DWR treatments across its performance-fabric line and specifically included NeoShell in that rollout. A non-PFAS DWR statement is relevant, but it does not by itself prove that every component in a finished jacket is PFAS-free or that a product meets every jurisdiction’s definition and threshold. Membranes, face fabrics, seam tapes, prints, zippers, trims, contamination controls, and supplier documentation may all need review.
Do not assume a blanket certification from the technology name. If a program requires OEKO-TEX, bluesign, recycled-content certification, a brand-specific RSL, or another scheme, request a current certificate or approval that clearly covers the exact style, facility, scope, and validity period.
Mise à jour actuelle de la réglementation et du marché
As of August 11, 2026, chemical restrictions are changing how waterproof shell materials are specified and documented.
The European Union’s Regulation (EU) 2024/2462 adds a restriction on PFHxA, its salts, and PFHxA-related substances. From 10 octobre 2026, consumer clothing and related accessories and consumer footwear may not be placed on the EU market or used at or above 25 ppb for the sum of PFHxA and its salts or 1,000 ppb for the sum of PFHxA-related substances, measured in homogeneous material. The regulation contains defined exemptions and transition provisions, so product scope must be checked carefully. FabricsTrades’ aperçu de la EU PFHxA restriction and textile supply-chain implications can help teams organize the issue, while the EUR-Lex text remains the legal source.
California’s AB 1817 rules have prohibited, with stated exceptions, the manufacture, distribution, sale, or offer for sale of new textile articles containing regulated PFAS since 1 janvier 2025. “Outdoor apparel for severe wet conditions” has a temporary exception until January 1, 2028, but covered products containing regulated PFAS require the statutory “Made with PFAS chemicals” disclosure from January 1, 2025. The law also requires a manufacturer certificate of compliance for covered textile articles. See the FabricsTrades explanation of California AB 1817 and the fabric supply chain for related reading, and verify obligations against the California Health and Safety Code.
For a NeoShell program, the practical response is to obtain an exact bill of materials, current declarations for the laminate and all garment components, destination-specific compliance review, and testing where contractually or legally required. Polartec’s non-PFAS DWR announcement is useful supplier evidence, but it should be supported by style-specific documentation and finished-product due diligence.
Market availability also needs confirmation. Polartec continues to reference NeoShell in official technology and partner content, but its main 2026 weather-protection category page highlights newer or currently emphasized lines. Confirm continuity, replacement options, sampling yardage, color minimums, and production lead times before approving a commercial calendar.
Sourcing NeoShell or a Suitable Alternative
Start with the garment’s conditions of use, not a membrane name. Define rain exposure, activity level, temperature range, expected stretch, pack or equipment abrasion, wash life, target weight, hand feel, noise, seam design, price, and destination markets.
For a jacket program, review suitable catégories de tissus de veste and, where mobility is central, available four-way stretch fabric options. These category links show sourcing directions; they do not imply that every listed fabric is NeoShell or a direct equivalent.
FabricsTrades is based in Wujiang District, Suzhou and operates its own four-way stretch fabric factory while also supporting sourcing, development, customization, and supply-chain coordination. For NeoShell or another branded laminate, availability and authorization should be confirmed for the specific project. FabricsTrades can help evaluate face-fabric options, arrange samples or lab dips where available, coordinate tests and inspection, and organize supplier documents based on the final specification.
Entretien et maintenance
Always follow the finished garment’s care label because adhesive systems, seam tape, prints, trims, and face fabrics can require different treatment. General good practice for waterproof-breathable shells includes:
- Close zippers and hook-and-loop fasteners before washing.
- Use cool or cold water and a mild detergent when permitted by the garment label.
- Avoid fabric softener because residue can interfere with moisture management and water-repellent surface behavior.
- Rinse thoroughly and avoid unnecessary high heat.
- Restore or renew the DWR only with a product and process approved for the garment.
- Repair damaged seam tape or delamination rather than relying on a surface treatment to stop leakage.
- For product development and quality claims, use controlled laundering such as ISO 6330 and retest critical performance after the agreed number of cycles.
Foire aux questions
Is NeoShell fabric waterproof?
Yes. Polartec describes NeoShell as waterproof and has published a 10,000 mm waterproof benchmark. Buyers should still verify the exact fabric style using a named hydrostatic-pressure method and test the finished garment’s seams and openings.
Is NeoShell more breathable than GORE-TEX?
NeoShell is intentionally air-permeable, but a universal “more breathable” claim is not technically sound without comparing specific products under the same test methods and conditions. Membrane version, face and backer fabrics, DWR condition, vents, fit, and laboratory method all affect the result.
What is NeoShell made from?
NeoShell uses an electrospun polyurethane-based fibrous membrane laminated to textile layers. The outer face and inner backer vary by style and may use different fibers and constructions.
Does every NeoShell fabric stretch?
No. Many NeoShell constructions are engineered for stretch or mobility, but stretch direction, percentage, recovery, and force depend on the selected face and backer. Request style-specific data and test the garment pattern.
Where is NeoShell manufactured?
NeoShell was developed in the United States, and Polartec’s current manufacturing overview identifies fabric formation in Hudson, New Hampshire and finishing in Cleveland, Tennessee. Buyers should request country-of-origin documents for the actual style and shipment rather than relying on a general brand statement.
Is NeoShell PFAS-free?
Polartec announced non-PFAS DWR treatments for NeoShell, but a finished-product PFAS claim requires review of the exact laminate, all trims and components, contamination controls, the destination law’s definition, and any required test evidence. A DWR statement alone is not a complete product compliance file.
How should brands test NeoShell before bulk production?
Brands should agree style-specific acceptance criteria for hydrostatic pressure, air permeability, surface wetting, moisture-vapor performance, strength, abrasion, delamination, colorfastness, and post-wash retention. They should also validate seam tape and run a finished-garment rain or leakage assessment appropriate to the use case.
Can FabricsTrades supply NeoShell fabric?
FabricsTrades can help evaluate sourcing routes and alternative constructions, but current NeoShell availability, authorization, MOQ, color minimums, and lead time must be confirmed for each project. Send the garment brief, target tests, quantity, color plan, destination market, and required documents before sampling.
Conclusion
NeoShell remains a useful reference point for air-permeable waterproof shells: it combines an electrospun membrane with style-specific textile layers to balance weather protection, comfort, and mobility. The right buying decision depends on the exact laminate, matched test data, seam construction, after-care performance, chemical documentation, availability, and intended use.
For a development project, prepare a measurable specification and compare an approved NeoShell style with any proposed alternative under the same tests. FabricsTrades can support material evaluation, sampling, customization, testing coordination, documentation review, and bulk-order assessment based on the final brief.
