This hardshell by Mountain Hardwear actually delivers. I've worn it on two different occasions in both cold and moist environments where staying dry and pushing hard were equally important. I wore it with only a base layer while hiking through Dolly Sods with six inches of snow on the ground and it breathed well without even opening the pitzips. The articulated sleeves kept the jacket from riding up, even while reaching overhead. It can cinch at the bottom of the hem or higher up to keep out cold air while working with a harness. The hood can be cinched tightly with one hand and stays put well. My body heat dries the surface completely in 15 minutes, so I wear it straight into the tent to enjoy being absolutely dry when it counts. Oh yeah, pockets everywhere.
