From a company with top-notch tents and sleeping bags comes a sweet line of puffies: the Gnar Jacket and the Gnar Hoody ($199, no hood; $209, with hood; sierradesigns.com). With 800-fill down, this jacket had a slim profile that was perfect as an insulating piece for a super-cold winter climb in Rocky Mountain National Park. (We turned around in white-out conditions about 200 vertical feet from the summit.) It also worked beautifully as a belay jacket on crisp fall days at Penitente Canyon. It’s got thumb loops and a thoughtful cut, with a cinch-cord waist and an elastic-rimmed hood. Note: Think about whether you’re most likely to wear it as a mid-layer or outer layer when opting for the hooded or non-hooded version—the hood could be a bit bulky with a hard shell layered over it.
