Rab Mythic Ultra 180 Sleeping Bag

The Mythic Ultra 180 redefines what it means to be 'ultralight'. Using a world-first, heat-reflective fabric treatment called Thermo Ionic Lining Technology, this is premium protection for those counting every last gram.

Designed and constructed by Rab technicians on the back of 40 years of hard-won mountain expertise, the Mythic Ultra 180 Sleeping Bag is one of the world's most advanced lightweight sleeping bags. Though constructed with an exceptionally light ripstop 7D outer and filled with high-loft 900+ fill power European goose 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 400g, the stripped back insulation of our TILT-equipped Mythic Ultra 180 is the ultimate expression of performance without penalty. An angled footbox allows for free movement within the sleeping bag for a warm yet unrestrictive feeling. The sleeping bag has a close-fitting internal collar with a hood drawcord to help retain the heat as well as a 1/8 length YKK anti-snag zip with an insulating draft tube to keep out the cold. Trapezoidal chambers also aid in the upkeep of warmth within the sleeping bag by eliminating cold spots so you can have a warm comfortable sleep.
