About eVent® fabrics and eVent membrane technology
In 1999, eVent® fabrics revolutionized technical outerwear with the introduction of a 100% waterproof, windproof and air permeable membrane that helps active users stay dry and comfortable in the widest range of temperatures and conditions. eVent fabrics—found in outdoor, winter sports, cycling, lifestyle and professional apparel, footwear and accessories—lets the sweat out through its patented Direct Venting membrane technology.


What is eVent® waterproof technology?
eVent® fabrics has set the standard for breathable performance in waterproof textiles with its patented air permeable ePTFE (expanded polytetrafluoroethylene) membrane technology. With billions of microscopic pores that instantly vent body heat and moisture vapor (sweat), eVent's proprietary Direct Venting technology keeps users dry and comfortable by helping prevent the clammy, chilly buildup of sweat. So no matter what the adventure or weather, eVent helps keep users dry and comfortable and performing their best.

How does eVent® Direct Venting technology work?
eVent's Direct Venting technology is engineered to keep the wearer in the "dry zone," where temperature and humidity are kept in a steady state during physical exertion. Because eVent air permeable technology "lets the sweat out," it eliminates the cycle of overheating, moisture buildup and cooling that wearers can experience during physical activity.

The result is that eVent helps people enjoy more time outdoors, even when weather conditions are at their worst.

How does eVent® Direct Venting technology differ from traditional waterproof/breathable fabrics?
eVent® Direct Venting technology creates a 'dry' system that allows eVent® fabrics to be fully breathable and waterproof the widest range of temperatures and conditions. Unlike other traditional waterproof/breathable fabrics, eVent technology does not use polyurethane (PU) in its membranes or laminates. PU systems must get 'wet' to work by absorbing body moisture, which is then pushed out by body heat. Instead, eVent Direct Venting technology efficiently and instantly lets body heat and sweat escape through the membrane's billions of microscopic pores.
