I took a fairly impressive spill and slid about 100 yards down a mountain side a few weeks ago. Didn't realize my coat came off my pack, which leads me to ask. With all new high speed low drag clothing options out there now, whats the best bang for your buck? I've got some mid layer sitka gear, but I don't think I can justify one of their big coats. Does anyone have first hand experience/ opinions about companies like first lite, nomad, ext. specifically the coats.
