Bin drove through the entire winter with it and excited. Even in freezing temperatures warm. The Kevlar coating in step protects the trousers effective against wear. Inside, the pants a fluffy network and also does not stick to the body so if you take a "hard working". Outside the pants of waterproofing material that sometimes holds out little rain. On the legs can be made narrower with two Velcro straps of the leg. This keeps the heat inside out and the leg from the chain. The legs can be separated well and then you have thereby also a Short. Rear also there still a small bag with zip. Vents on the thighs (with zip) round out the cause. The higher price is due to the quality and especially the functionality in my opinion justified (typical Gore).
