Product Description

The Mythic Ultra 180 Long is a lightweight mummy down sleeping bag built for spring and autumn camping trips. Its long cut (230 x 81 cm) gives taller users extra space, and it’s rated to keep women comfortable down to +7 °C and men to +2 °C on cool nights.

With 180 g of European goose down at 900-fill power, treated with a fluorocarbon-free hydrophobic finish, this bag strikes a balance between warmth and packability while resisting moisture to maintain loft. The 100 % nylon shell and lining are both light and robust, and at just 440 g it tucks easily into a backpack without adding bulk.

Fill power (FP) indicates how much space one ounce of down fills—a 900 FP rating means higher loft and better insulation per gram of fill. The hydrophobic treatment helps the down shed water and dry faster, so it stays fluffy and warm even in damp conditions. The mummy shape tapers toward the feet, reducing excess air space around your body and improving heat retention.

RAB says about the Mythic Ultra 180 Long

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 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 an exceptionally light ripstop 7D outer and filled with high-loft 900+FP 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.
