Rab Mythic Ultra 360 -8 Sleeping Bag (645 Grams)

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

For mountain marathon runners and committed alpinists who need to travel light, the Mythic Ultra 360 is a game changer./

Built from lightweight recycled 10D Atmos, it uses Thermo Ionic Lining Technology (TILT) to coat the fibres with titanium, helping reflect radiant heat back towards your body without compromising the fabrics breathability. While that reduces the amount of down required for a given level of warmth, the angles of the bags trapezoidal boxwall construction also improve the evenness of down distribution, eliminating cold spots.

Filled in the UK with 900FP down and weighing in at just 645g, the Mythic Ultra 360 provides one of the most efficient warmth-to-weight ratios available.

WHAT IS TILT?The inner lining uses Thermo Ionic Lining Technology (TILT) which reduces radiative heat loss by reflecting heat back towards the body resulting in increased levels of warmth. This dramatically increases the Mythic Ultras warmth-to-weight ratio without changing the original fabrics properties or increasing weight.
