All eVent fabrics protect you from the wind. And, all eVent fabrics provide you with sweat-free comfort through our unique Direct Venting™ Technology. Garments, gloves and footwear made with eVent Waterproof fabric add another level of protection. Patented surface treatments and fabrication methods keep out water - even hard-driving rains - without blocking those millions of tiny pores thatlet the sweat out.™.
eVent fabrics get their unique properties from a proprietary and patented waterproof membrane. Its unique composition allows millions of tiny pores to breathe at their full potential. Sweat vents directly to the outside of the fabric in one easy step. We call this Direct Venting™ Technology. Its genius is hidden in its simplicity. eVent fabrics simply let the sweat out.™
Most common waterproof/breathable technologies do not literally "breathe". Instead they move sweat in two slow steps by a process of diffusion through a Polyurethane (PU) layer. First sweat is condensed and absorbed into the PU layer on the inside of the fabric. Because PU absorbs and retains sweat, the inside of the fabric becomes wet. Then, body heat begins to push that dampness through to the outside of the fabric where it can finally evaporate - a very inefficient process.
eVent fabrics provide durable waterproof protection, trusted by people like you in the most extreme weather conditions on the planet.
We could mention the exceptionally low "Water Vapor Resistance" (RET) of eVent fabrics. Or, we could talk about how much higher our "Moisture Vapor Transmission Rates" (MVTR) are in laboratory tests. But, do you run in the lab? Do you ice climb inside a climate chamber? The bottom line is decided in the field. Out there it's a black and white world: you're either wet or dry. You either soak in your own sweat, or not. It's that simple. eVent fabrics let the sweat out.™
