Technologies

Gore-Tex®

Gore-Tex® fabrics offer long-lasting, comfortable weather protection. The technology is based on an extremely thin membrane made of expanded polytetrafluoroethylene (ePTFE). Its pores are too small for rain to penetrate, yet big enough for perspiration to pass right through. Gore-Tex® products have a high waterproof rating (water column) and can withstand up to 28,000 mm of water pressure – more than monsoon rain. The membrane is bonded between an outer fabric and a high-performance lining. Depending on the construction, the result is either a 2-layer, 2.5-layer or 3-layer laminate. Gore-Tex® in a 3-layer construction offers a combination of enhanced durability and high breathability, while the 2-layer laminate provides lightweight weather protection.

VIBRAM®

Vibram® soles, thanks to the combination of hyper-functional design and exclusive rubber compounds, ensure best performances in terms of comfort and lasting quality.
