What Is It?

Our proprietary lamination repels rain on the outside and minimizes sweat next to skin. With a minimum of 10K/10K performance, it balances long-lasting waterproofness with soft, quiet, and breathable comfort.

How Does It Work?

When condensation is converted into vapor, it creates a chilling effect. Paired with superior face fabrics, MemBrain’s hydrophilic PU lamination helps prevents the chill while also keeping you comfortable in Mother Nature’s worst elements.
