š± Hereās a little behind-the-scenes action from AO HQ. Prototype No2 of our GT Waterproof arrived recently, taking in a few adjustments to the original sample. The outer shell on these things is a 3-layer nylon fabric with a waterproof rating of 20,000mm and a breathability rating of 10,000g/m2. In simple terms that means these things are waterproof AF, but still with a decent level of breathability so you wonāt overheat. Obviously theyāve been off to the lab to have their ratings double and triple-checked by people in white coats, but thereās nothing like testing it for yourself. Here you see us doing a spot of home-made ultra high-tech shower testing. So it was on with the grey sweatshirt (so that any water ingress would show up nicely), shower on full wallop, and 25 minutes of cold water hammering on the jacket. The result? A confidence-bolstering bone-dry interior and a Gold Star from the AO lab. Full production run is now under way, finished products on the way!
