Technical fabrics

Shelltec ActiveShelltec Active fabric provides very high levels of waterproofing and breathability along with a windproof barrier thanks to its membrane (20000mm water column and vapor permeability of 20000grs xm2 x24h). Designed to be worn as an outer layer, Shelltec Active fabric has been developed to minimize heat loss on exposure to wind and rain. This fabric is ideal for intense and aerobic outdoor activities when bad weather makes high external protection essential.
