hen there's some backcountry exploration on the agenda, the Killtec Siranya Insulated  will be along for the ride. These pants have a four-way stretch that will move with you as you make your way through the tree lines. A 10K waterproof rating and 60g of insulation will keep you warm and dry even in fresh powder. Boot gaiters will seal out the snow as you move through some knee-deep powder before heading back to the groomed trail down to the ski lodge for some lunch.
