The Mythic Ultra Down Jacket has the best warmth-to-weight ratio Rab have ever achieved in an alpine down jacket. Combining advanced heat-retaining TILT technology with the lightest, strongest fabrics available, as well as near-mythical 900 fill-power goose down's unrivalled warmth-for-weight. To improve performance, a combination of different baffle types are used. Lightweight stitch through-baffles on the arms and hood improve mobility, while boxwall baffles around the core encourage the down to loft fully, maximising heat trapping. Because the baffles are offset, the down is distributed evenly around the core, reducing the possibility of cold spots. Mythic Ultra Down Jacket - Women's
