A waterproof stretch fabric made from a blend of tough durable nylon and elastane for stretch. The stretch is two way so the length of the garment is unaffected by tugs and strains, only the width is variable which gives easy movement whilst scrambling across difficult terrain.
This is described as a 2.5 layer fabric. The waterproof and breathable polyurethane layer is protected on the outside by the tough nylon / elastane shell whilst the inside is protected by a black and white print pattern.
The Hydrostatic Head is 5,000 mm meaning that the material will hold back a five metre high column of water. The minimum Breathability is 5000 gms/sq metre/every 24 hours. Meaning that 5 litres of water in the form of vapour will pass through the pours of the garment every 24 hrs.
The outer surface is protected by a DWR Durable Water Repellant coating which causes rainwater to bead up and run off, thereby preventing the surface from wetting out. This aids breathability so your perspiration can escape even when its raining.
A hydrophilic, water loving coating on the inside of the fabric helps with the absorption and transmission of water vapour. Hence the fabric feels less clammy and more comfortable to the wearer.
