Outdoor Research Men's Archangel Bibs Built for and by alpine climbers, the Archangel Bibs let you pursue the biggest objectives with the gold standard of 3L protection. Complete elemental protection and mobility are the ethos of the Archangel, developed in close collaboration with OR Ambassador Graham Zimmerman. The Archangel Bibs use stretch panels where you need it on the knees, lower back, and crotch gusset, and ankle cuffs adjust in size for both mountaineering and ski touring boots.
