Experience superior warmth without the weight with the Mythic Ultralight Down Jacket, a top-tier down jacket ideal for frigid conditions. Featuring innovative heat reflective technology, this featherlight and packable jacket is a must-have for mountain athletes, outdoor pros, and fast-paced alpinists.

Rab set out to craft an alpine down jacket boasting the best warmth-to-weight ratio ever achieved. By merging advanced heat-retaining TILT technology with ultra-lightweight yet strong fabrics, along with the exceptional warmth of goose down, we’ve developed something revolutionary. The unique baffle construction maximizes performance—lightweight stitch-through baffles on the arms and hood enhance mobility while boxwall baffles around the torso ensure optimal lofting of down for maximum heat retention. With offset baffles, we’ve evenly distributed down around the core to minimize cold spots.

Following extensive research and development, we discovered that placing the TILT layer as close to your body as possible dramatically improves heat retention. This reflective layer gives the Mythic Ultralight Down Jacket a significant boost in thermal efficiency—perfect for chilly belays or icy summits. To keep things light, we've utilized an ultralight 10D outer fabric that's 100% recycled. This Pertex® Quantum material is robust, durable against weather elements, soft to touch, and features built-in ripstop.

Engineered for alpinists and mountaineers alike, it includes a helmet-compatible hood, a two-way front zipper designed for harness use, and finely tuned sleeve articulation perfect for climbing challenges. All zippers and adjusters are crafted with lightweight convenience in mind.

The Mythic Ultralight has earned accolades like the ISPO Award 2022 and GearJunkie’s “Best in Show," highlighting its cutting-edge technology and construction—a true game changer for mountain enthusiasts who prioritize weight savings.
