The Stretchdown Light Jacket packs small and performs big when conditions change

What Our Gearhead® Experts Are Saying:


"The Stretchdown Light Jacket has become my permanent pack-along layer because it stuffs down so small I genuinely forget it is there until a cloud rolls in or the wind picks up. The stretch woven fabric moves completely freely on technical terrain, and the 700-fill down delivers real warmth for how little the jacket actually weighs."


The best insurance against changing mountain weather is a layer small enough to always bring along, and the Mountain Hardwear Stretchdown Light Jacket makes that decision effortless. As the most compressible version in the Stretchdown lineup, it packs directly into its own right hand pocket and disappears into a pack, hip belt, or cargo pocket without demanding any real estate in return.


What comes out when conditions shift is a 700-fill RDS certified down jacket that punches well above its packed size, delivering genuine warmth through the same Stretchdown construction that weaves insulation into a single stretch doubleweave fabric rather than trapping it between layers. The 20D nylon and elastane blend moves through the full range of climbing and hiking motion without restriction, and elastic cuffs seal warmth at the wrists when the temperature drops on a ridge or at a high camp belay. With only 2.9 ounces of insulation keeping things lean and light, the Stretchdown Light Jacket is the layer that costs almost nothing to carry and delivers everything when it counts.
