Athletic-fit ski-mountaineering trousers that combine hard-wearing and protective panels over the front with a soft, comfortable thermal back - to deliver a pair of truly versatile hybrid trousers. They are constructed using two main materials: the front is in Endurance, a 2-way stretch soft shell, now more protective and water-repellent thanks to the DWR finish - yet equally breathable; the back is in Vuelta, the lighter weight, high-stretch fabric made in Italy - for maximum freedom of movement. The knees are articulated and finished with a pattern that reaches down to the inside panels at the bottom of the legs, made of a durable double-weave stretch fabric.
