Rab Mythic Ultra Jacket

More warmth for fewer grams, this is the ultimate ultralight, multi-award winning down jacket for freezing temperatures. Heat reflective tech, featherlight, and packable, it’s a game changer for mountain athletes, outdoor professionals, fast-moving alpinists or upscale around town kinda warmth.



This is a top pick for an alpine down jacket that has the best ever warmth to weight ratio.

  • It combines advanced heat retaining TILT technology with the lightest, strongest fabrics, and the unbeatable warmth-for-weight of goose down.
  • The combination of baffles maximize performance.
  • Lightweight stitch through-baffles on the arms and hood give better mobility, and boxwall baffles around the core encourage the down to fully loft maximizing heat trapping.
  • The baffles are offset, which distributes the down evenly around the core and reduces the chance of any cold spots.

After extensive R&D Rab found that positioning the layer of TILT as close to the body as possible maximised heat retention. This heat reflective layer gives the Mythic Ultra Jacket a noticeable boost in thermal efficiency, welcome warmth on frigid belays and frozen summits.

To keep weight at a minimum they used an ultralight 10D outer which is 100% recycled. This Pertex® Quantum fabric with built-in ripstop is strong, durable, weather protective and feels soft to the touch.

Often chosen by and perfected for alpinists and mountaineers, it has a helmet compatible hood, two-way front zip for use with a harness, and fine-tuned articulation through the sleeves for climbing. All zips, adjusters and the stuff sack have been designed to be lightweight and low bulk.

Scooping up both an ISPO Award 2022 and GearJunkie’s “Best in Show” celebrating future-leading technology and construction, the Mythic Ultra is a game changer for mountain athletes who count every gram.
