A closer look
Rab’s goal was to create an alpine down jacket with their best ever warmth to weight ratio. Achieved by combining their advanced heat retaining TILT technology with the lightest, strongest fabric they could find, with unbeatable warmth-for-weight of goose down. After extensive R&D they 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, creating welcome warmth on frigid belays and frozen summits.

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.

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.

Pertex Quantum is a lightweight, windproof fabric with a tightly women structure. Highly packable and protective, it’s ideal for mountain activities.
