As a long time user of pile/ pertex, I was interested to see what a garment made from Polartec Alpha Direct was going to be like. So far, I am very pleased with the fit, comfort and weight. Coming from a Buffalo Shirt, the Hydrogen Extreme Smock follows a similar pattern but is roughly half the weight. The Alpha Direct is super soft against the skin and the Pertex Quantum Air/ Pro shell is also extremely soft, thus not sounding like an empty packet of crisps. I've yet to thoroughly test this smock in a range of weather conditions but I am very happy so far. I'll provide a further update in the future.
