The InderShield™
Membrane
How InderShield™ redefines waterproof-breathable protection without PFAS
The answer lies in a fundamentally different membrane architecture. InderShield™ features a proprietary monolithic membrane construction engineered to achieve best-in-class MVTR performance while maintaining durable waterproof protection. Unlike microporous technologies, InderShield™ has no pores to clog, contaminate, or degrade over time.
Crafted from 100% polyurethane, the membrane utilizes advanced hydrophilic technology that actively transports moisture vapor away from the body while creating a complete barrier against liquid water. The result is a more durable waterproof-breathable solution that delivers both high moisture vapor transmission and long-lasting waterproof performance.
Unmatched Waterproof
Performance
Our membrane was engineered for durable waterproof performance — the foundational promise of high-performance outerwear, achieved without compromise.
Raising
the Bar
Our membrane enables waterproof performance up to 50,000mm hydrostatic head — scalable from hyper lightweight rain protection to the most extreme wet conditions on the planet.
Rapid
Breathability
InderShield™'s proprietary membrane structure pushes monolithic membrane performance to a new level. Engineered to maximize moisture vapor transmission without compromising waterproof durability, the InderShield™ membrane enables exceptionally rapid vapor transport through the material, outperforming legacy microporous & monolithic solutions.
Built to
Your Spec
Our membrane enables moisture vapor transmission rates up to 45,000 g/m²/24h. The membrane is applicable to a wide variety of products — from highly breathable, hyper-lightweight fabrics to rugged, extremely waterproof constructions.
Blocks
Wind
Our fully windproof membrane acts as a barrier against heat loss caused by moving air, helping maintain a stable microclimate around the body. By blocking external wind while allowing moisture vapor to escape, it delivers lasting comfort, effective temperature regulation, and reliable protection in demanding conditions.
Innovative
Lamination
Method
We have proprietary methods to bond our membrane to face fabrics and backers — creating finished laminated products that perform as a unified system, not just layered components. Bonded to face fabrics and backers it produces a finished, high-performing waterproof-breathable fabric applicable to garments, shoes, gloves, accessories, and more.
Our Commitment to
Ongoing Innovation
From our founding commitment to PFAS-free performance to our ongoing research into next-generation membrane technology, InderShield™ continues to push the boundaries of what waterproof-breathable fabrics can achieve.
