Slotting in as the fully-featured bib option from Marmot, the Refuge Pro Bib leaves little to be desired when we're chasing summits in the backcountry or freeriding pristine powder at the resort. These bibs feature Marmot's NanoPro 3L membrane for waterproofing that's designed to last through heavy storms, plus it's ultra-breathable so that we don't feel bogged down on the skintrack.
