With its world-first heat-reflective Thermo Ionic Lining Technology, the Rab Mythic Ultra 360 sleeping bag delivers pioneering protection for those who need to make every gram count.

For mountain marathon runners and high-end alpinists who need to travel light, the Mythic Ultra 360 is a game changer. Built from ultralightweight 7D ripstop nylon, it uses Thermo Ionic Lining Technology (TILT) to coat the fibres with titanium, helping reflect the user’s radiant heat back into the bag without compromising the fabric’s breathability. While that reduces the amount of down required for a given level of warmth, the angles of the bag’s trapezoidal boxwall construction also improve the evenness of down distribution, eliminating cold spots.

Filled in the UK with 900FP down, a weight of just 606g ensures the Mythic Ultra 360 provides one of the most efficient warmth-to-weight ratios in the world.
