Shop with confidence. If it’s not working out, you can return it (consumables, electronics, undergarments and swimwear excluded).
Really. If it's not up to snuff after you use it (a couple times) you can still bring it back. It lasts longer than 30 days, but not forever. We'll be fair about it.


Embrace cold-weather backpacking, knowing your puffy has you covered. While some down jackets tear and bleed down at the touch of a twig, the Diamond Fuse fabric stands up to rigours of the trail without adding extra weight. The high fill-power down and durable fabric all pack down small, stuffing into its own pocket during bluebird days.

  • Pertex® Quantum nylon ripstop is highly abrasion-resistant, and has a DWR finish
  • Diamond Fuse technology uses tightly woven, diamond-shaped filaments for improved abrasion- and water-resistance
  • 800+ fill-power goose down comes from ethically produced sources
  • Elastic wrist bindings and drawcord hem seal out drafts
  • Left pocket doubles as a stuff sack
