The StretchDown Jacket goes from trailhead to summit without slowing you down

What Our Gearhead® Experts Are Saying:

"I have been wearing the StretchDown Jacket as my go-to midlayer on alpine climbing days where mobility is non-negotiable, and the stretch woven fabric genuinely delivers in a way that most insulated jackets simply do not. The 700-fill down keeps me warm during belays and the fabric moves completely freely when I am pulling on holds or reaching for gear overhead."

Most insulated jackets make you choose between warmth and movement. The Mountain Hardwear StretchDown Jacket refuses that compromise. Built around the brand's exclusive Stretchdown technology, it weaves 700-fill down insulation directly into a single stretch fabric rather than trapping it between layers, creating a construction that moves with the body instead of fighting against it.

The 20D durable stretch doubleweave nylon and elastane blend delivers remarkable four-way stretch that keeps up with everything from dynamic climbing moves to long trail approaches without bunching, pulling, or restricting reach in any direction. Elastic cuffs and dual lower hem adjusters seal in warmth when conditions tighten up, while a two-way center front zipper allows ventilation on high-output efforts. Zippered chest and hand pockets keep essentials organized and secure, and an internal drop pocket handles anything that needs to stay closer to the body. RDS certified 700-fill down confirms both quality insulation and responsible animal welfare standards from source to final product, making the StretchDown Jacket a layer that performs without compromise on any front.
