About this product

The Rab Mythic Ultra 180 is a high-performance ultralight sleeping bag rated to a sleep limit of 0 degrees Celsius (32 degrees Fahrenheit), designed for weight-conscious mountaineers and backpackers. At just 400 grams (14.1 oz), it achieves this low packed weight through a combination of a 7D ripstop nylon outer shell and 900+ fill power RDS-certified European goose down, treated with a fluorocarbon-free hydrophobic finish developed in partnership with Nikwax. 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 to the sleeper, boosting warmth without adding weight or reducing breathability. Construction details include a trapezoidal chamber design to eliminate cold spots, a saving baffle to prevent down migration, a proportionally designed differential cut, and an ergonomic internal collar and hood. The bag measures 215 cm (86.5 in) in length with a 70 cm shoulder width, 52 cm hip width, and 41 cm foot width, fitting users up to 185 cm tall. A left-hand YKK 3-coil zip with a noctilucent puller, a dry bag stuff sack, and a cotton storage sack are included. Filled in Derbyshire, UK.

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.
