About this product

The Rab Mythic Ultra 180 is a three-season sleeping bag built around an obsessive focus on weight reduction, tipping the scales at just 400g (14.1oz) while delivering a 0°C (32°F) sleep limit rating. Its outer shell is a super-lightweight 7D ripstop nylon, and the fill is 900+ fill power RDS-certified European goose down treated with Rab's fluorocarbon-free Nikwax Hydrophobic Down process to resist moisture. The standout feature is the inner lining, which uses Thermo Ionic Lining Technology (TILT), a titanium coating applied to the fibres that reflects body heat back toward the sleeper, boosting warmth without adding weight or reducing breathability. Construction details include a trapezoidal baffle chamber design to eliminate cold spots, a proportionally cut differential shell, an ergonomic internal collar and hood, an angled foot box, and an anti-snag bonded zip guard on the 1/8-length YKK 3-coil main zip. Internal dimensions include a 70cm shoulder width, 52cm hip width, and 41cm foot width across a 215cm total length. The bag is filled in Derbyshire, UK, and ships with a lightweight dry bag stuff sack and a cotton storage sack.

What people are saying

Reviewers consistently praise the Rab Mythic Ultra 180 for its exceptional warmth-to-weight ratio, with its sub-400g weight and 900+ fill-power hydrophobic down earning widespread admiration among ultralight backpackers and fastpackers. The proprietary TILT titanium heat-reflective lining is frequently highlighted as a genuine innovation, boosting warmth without adding bulk or trapping moisture. The well-designed baffles, comfortable hood, internal collar, and angled foot box also draw consistent praise. The most common criticism centers on the very short entrance zipper, which makes getting in and out awkward and can stress stitching, particularly for taller or larger users. Cold sleepers also note that the 0C comfort rating should be treated as a guideline, with extra layers recommended near the temperature limit. The premium price point is another recurring concern.
