Product information
HDry ‘b5’ membrane is the biobased version of HDry 3D direct lamination technology for footwear. HDry ‘b5’ is made from 53% renewable plant sources, PTFE-free, PFAS-free and Oeko-Tex certified. The patented HDry ‘3D direct lamination’ process bonds the waterproof / breathable membrane directly to the upper material, blocking water at the outermost level. At the same time, it eliminates the gap between the outer layer and the membrane, (typical of ‘bootie’ lining construction) and the risk of moisture accumulation: the weight is significantly reduced, and boots take much less time to dry.

HDry - Altexa srl
The insight that steered HDry's technological development is simple: move the waterproof and breathable barrier as far outside as possible to block the ingress of water to the outermost layer and prevent its penetration inside the shoe or equipment item. The HDry waterproof and breathable membrane is directly laminated to the inner side of the upper by a patented 3D lamination process and machinery, sealing the material and all seams in one step (tapeless). Water cannot penetrate the outer surface, so the boot stays much lighter, and feet remain dry and comfortable in any weather condition. HDry performance is tested according to: SATRA TM444 (waterproofness by STM640 centrifuge), TM376 (moisture management). HDry is PTFE-free, PFC’s free and OEKO-TEX STANDARD 100 certified. HDry 'b5', the high performance bio-based membrane is now available too.
