Sympatex® is a high-tech, hydrophilic, non-porous membrane that is 100% waterproof and windproof, yet breathable. The hydrophilic components of the membrane absorb moisture from the body and expel it outwards.
The result is excellent comfort, with exceptional performance in all weather conditions, even in the most extreme situations.
