For the ultimate in nasty weather, youll want the ultimate in down coats. The Mountain Hardwear Sub Zero SL Parka covers you in 650-fill down to keep you warm, and is made with Conduit laminate to be water- and windproof. Nutshell Taslan reinforcement is super tough to resist the ravages of pack straps, rock and the rest of the abuse you put your poor, innocent coats through. The Parka compresses down mind-bendingly small into the included stuff sack. The Sub Zeros down-filled hood gives you super warmth for super cold conditions, and it snaps off easily. Baffle construction keeps the down where it belongs so it doesnt all shift to one end of the coat.
