When our ski or snowboard mission in the backcountry calls for ropes and crampons we feel comfortable in the Mountain Hardwear Routefinder GORE-TEX PRO Bib Pant. While these bibs certainly hold their own when skiing and snowboarding thanks to a waterproof and breathable GORE-TEX laminate they really thrive on mountaineering missions thanks to full-length external zippers and reliable button cuffs that adapt to our boot of choice.
