What Our Gearhead(R) Experts Are Saying:"I wore this as a midlayer through a full season of shoulder season hikes and it earned a permanent spot in my pack. The PrimaLoft insulation kept me warm without any bulk, and it packs down small enough that I barely notice it's there until I need it."Shoulder season hikes and unpredictable mountain weather both call for a layer that can adapt on the fly, and the Primaloft Packaway Air Hoodie is built for exactly that kind of versatility, now at Backcountry from L. L. Bean. The windproof, water resistant Pertex Quantum Air shell handles gusty ridgelines and light precipitation with ease, whether worn alone on a mild afternoon or layered under a shell when conditions turn. Falling at the hip with a slightly fitted cut, it moves easily through scrambles, climbs, and long stretches of trail. Inside, 40 gram PrimaLoft Gold Insulation with Cross Core technology uses NASA developed Aerogel for serious warmth without added weight, keeping the whole jacket packable enough to stow away when temperatures rise. Two zippered hand pockets and a zip chest pocket keep essentials secure, and the whole hoodie compresses into its own stow pocket for easy carry on the trail or in transit.
