It can't always be summer at the crag, but you really mind late autumn climbs because Mountain Hardwear's Rhea Ridge Pullover is perfect at keeping you warm while you belay. This lofty down pullover puffy is chock-full of RDS-certified down, meaning these birds were never subjected to force-feeding or live plucking, and in return their plumage provides you with lightweight heat-trapping wonder, the kind you'll never want to take off. Since the puffy is so light, you'll hardly notice it in your pack if you take it while you're on-trail, and yet it comes equipped with a nice warm hood, zippered kangaroo pocket for your snacks, and plenty of pizzazz.
