Direct Venting™ Technology

Dachstein trusts eVent® fabrics. eVent® fabric lets sweat escape up to twice as fast as common waterproof and breathable membranes.

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. This is called Direct Venting™ Technology. Its genius is hidden in its simplicity. eVent® fabrics simply let the sweat out.

Forerunners: PU membranes

Most common waterproof / breathable membranes do not literally “breathe”. Instead they move sweat in two slow steps by a process of diffusion through a Polyurethan (PU) layer. 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.
