Breathable Waterproof Laminate Fabrics with 37.5TM Technology

Our extremely breathable polyurethane laminate fabrics with 37.5 technology have excellent moisture vapor transmission rates (MVTR) for high-performance use in outerwear, footwear, and gloves. Available in 2.5 layer and the world’s first 3.5 layer, each laminate component is optimized for highest breathability while maintaining waterproofness. We use a proprietary high-MVTR hydrophilic membrane, adhesive that’s optimized for high MVTR while maintaining durability, and a finish print with patented 37.5 active particles that use body heat to speed evaporation so you stay dry and comfortable. The result: innovative laminate fabrics that move moisture to keep you dry on the inside as well as the outside.
