Men's Mythic Ultra Down Jacket

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

Rab's goal was to create an alpine down jacket with our best ever warmth to weight ratio. Rab set to work combining our advanced heat retaining TILT technology with the lightest, strongest fabrics they could find, and the unbeatable warmth-for-weight of goose down. Rab also used a combination of baffles to maximise 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 maximising 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 Rab 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.

Designed for use by 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.
