The Mythic Ultra 180 redefines ultralight warmth. Using our ground-breaking heat reflective Thermo Ionic Lining Technology, this is premium protection for those counting every last gram.
Rab says:
Designed and constructed by our in-house technicians on the back of 40 years of hard-won mountain expertise, the award-winning Mythic Ultra 180 is one of the world’s most advanced lightweight sleeping bags.
Though constructed with a lightweight recycled 10D outer and filled with high-loft 900FP down, the really special part is the inner lining. This incorporates world-first Thermo Ionic Lining Technology (TILT), which adds a titanium coating to the fibres to reflect heat back towards your body, enabling it to significantly boost warmth without increasing weight, compromising breathability, or sacrificing any features.
Weighing just 440g, the stripped back insulation of our TILT-equipped Mythic Ultra 180 is the ultimate expression of performance without penalty.
