Outdoor Research Hyak Pants

Summit Hut says:
The Outdoor Research Hyak Pants are designed with a simple and streamlined feature set that gives you just what you need for fall snowshoeing and spring ski touring, without the weight or bulk of winter. Articulated knees and a gusseted crotch aid the fabric's naturally movement-enhancing stretch, and an inner drawcord at the ankle allows you to cinch your pants tight to keep out snow or watch your toehold. Plus, the Hyak Pants feature a waistband that's amplified by ActiveTemp, the thermo-regulating technology that adjusts to your body temperature to keep you cool, dry, and comfortable during high-exertion activities.
