Spoiling us with the comfort of a softshell and the protection of a hardshell, the Rab Khroma Kinetic Bib Pant is our pick for ski touring and mountaineering. Made with Rab's softest hardshell material, the bibs feature high waterproof and breathability ratings to protect us from the elements and dump excess body heat and moisture when we're running hot in the cold. It's a good pick for high-output winter activities-and for those of us who prioritize breathability and stretch in our shells.
