What Our Gearhead® Experts Are Saying: "I wear the Stretchdown Jacket constantly—from chilly morning hikes to everyday errands. The stretchy fabric moves with me, and the 700-fill down packs serious warmth without feeling bulky. It's the jacket I throw in my pack for everything short of a snowstorm." When we need warmth without restriction, we reach for the Mountain Hardwear Stretchdown Jacket. Built with movement in mind, this unique piece weaves together 700-fill down insulation inside a single stretch fabric, giving us both mobility and reliable heat. From crisp trailheads to breezy summits or layering under a waterproof shell in stormy weather, it’s a do-it-all insulator that we keep close all winter long. Mountain Hardwear engineered the Stretchdown with a durable doubleweave fabric that stretches with every reach, scramble, and stride. A two-way front zip makes for easy ventilation during high-output hikes, while zippered hand and chest pockets keep the essentials close. Elastic cuffs and a dual-adjustable hem seal in warmth, and the RDS-certified down keeps our conscience clear with ethically sourced insulation.
