Stio Colter Down Jacket (Men's)
This toasty 650-fill puffy is one of our go-to layers for winter crag days: the two-way zipper allows you to flare out the hem over a harness for an easy belay. We prefer the Colter for less aerobic outings, but if you’re working up a sweat, it has pit zips for dumping heat. Bonus: the brushed tricot in the pockets and interior collar provide a boost of comfort in frigid temps.
