How does the waterproof membrane work?
The membrane is a hydrophilic, polyurethane membrane specially developed by Porvair. It is non-porous (solid layer) and therefore does not allow water droplets to penetrate. This means it is totally waterproof : in waterproof tests the membrane exceeds 300cms hydrostatic head – 3 times greater than the level required to meet European Standards for waterproof clothing.
