3.3 oz Ventek™ 30 WPB

The result of over a year of development, testing, and pushing limits,Ventek is our custom designed, high-performance WPB fabric line. Waterproof/Breathable (aka WPB) fabric is exactly what the name implies -bothwaterproof ANDbreathable. To achieve this, WPB fabric uses a specially formulated laminate film that is highly resistant to water droplet penetration (i.e. rain) while also allowing moisture vapor (i.e. sweat) to pass through and escape. 3.3 oz Ventek 30 is a 3-layer WPB fabric designed to balance weight and durability while maintaining performance (waterproofness and breathability) that rivals big names like Gore-Tex and eVent. Great for a wide range of applications such as jackets, over mittens, gaiters, pants, ponchos, bivy shells, and more.
