The STORMTECH H2X® coating prevents even the smallest of raindrops from penetrating fabrics – yet at the same time, H2X® allows perspiration vapour to escape.
The inside of each STORMTECH H2X® garment is applied with a permanent microporous coating to ensure waterproof protection ranging from 1,000-5,000 mm. That means that if all of the rain drops hitting your jacket could stack on top of each other – they would have to stack up to 1-5 meters before the water could exert enough pressure to soak through and get you wet!

H2X® Technology also ensures fabric breathability of 1,000-5,000g/m2/24hr. This factor ensures that the garment allows perspiration vapour to readily escape, and provide maximum comfort and dryness for the wearer.
All STORMTECH H2X® & H2XTREME™ jackets are rated in terms of their breathability and waterproof protection, to help you select the jacket that best suits your needs.
