The higher you get the worse the weather becomes, but the Mountain Hardwear Women's Torsun Jacket is fully equipped to handle the gnarliest alpine storms. It's fully waterproof and built with a three layer Dry. Q Elite Instant waterproof and breathable membrane, which begins transporting moisture as soon as you put it on, unlike most shells, which require moisture to build up inside the jacket before it begins to breathe. Mountain Hardwear made sure that the elbows were fully articulated for supreme mobility when you're working your way through the crux, and constructed the shell from rugged 40D nylon, so you don't have to worry about tearing it up when things get tight and grabby. The harness and pack compatible hand pockets also double as vents, so you can dump heat when you're working hard to get to summit.
