Whether we're making a 4 a.m. summit push, ripping skins on bone-chilling dawn patrols, or standing at belay while our buddy figures out the crux moves, we count on the Mountain Hardwear Ghost Whisperer 2 Hooded Down Jacket to fend off the cold without adding a bunch of weight. With a weight of only 8.8-ounces, the Ghost Whisperer 2 is the lightest in its class, and it uses Q.shield-treated, 800-fill goose down insulation that maintains impressive loft, even when wet, to keep us warm and cozy.
