Rab Mythic Ultra 180 Down Sleeping Bag – Zipper Left – Black

The Mythic Ultra 180 completely redefines the term “ultralight”. Using a world-first heat-reflective fabric treatment called Thermo Ion Lining Technology, it offers premium protection at an extremely low weight.

Designed and manufactured by Rab’s product developers based on 40 years of mountain experience, the award-winning Mythic Ultra 180 is one of the most advanced lightweight sleeping bags in the world. It’s constructed with exceptionally lightweight ripstop 7D outer fabric and filled with high-bulking 900+ cuin European goose down. But what makes it truly special is its inner lining. This features the world’s first thermo-ionic lining technology (TILT), which applies a titanium coating to the fibers to reflect heat toward the body. This allows for a significant increase in heat retention – without heavier weight, compromising breathability, or compromising other features.

Weighing just 400g, the minimalist insulation of the TILT-equipped Mythic Ultra 180 is the ultimate in uncompromising performance.

What is TILT?

The Thermo Ionic Lining Technology (TILT) liner reduces radiant heat loss by reflecting heat radiation back into the sleeping bag. This ensures cozy warmth. This optimizes the warmth-to-weight ratio without compromising the original properties of the fabric or the weight of the sleeping bag.
