I've worn some Schoeller pants on snow and rock I find them to be about the most flexible garment I've ever worn. The are very water repellent, very breathable, are comfortable in a wide range of temps and, contrary to what some say, I have found them to be quite durable/abrasion resistant. I got mine from L.L. Bean and while I am not usually a fan of their stuff (except the venerable Maine Hunting Shoe) I have been very happy with them. They are not so expensive from Bean.
