I purchased these pants this winter. The fit and feel were great, and I couldnt wait to try them out. I had an old pair of marmot gore tex pants that I had been using for mountaineering for several years. On my first trip, I ripped an eight inch gash across the butt after barely touching the topside of my snow shoe as I was sitting down. The positive was the service from BC. They replaced the pants no questions. I gave the new pair of exum pants another chance this past weekend in Baxter, and the second day, another tear across the knee from brushing up against my trekking pole. This material is like aluminum foil. I would not recommend these pants unless you plan on using them while sitting in a rocking chair.
