About this product

The Rab Mythic Ultra 180 is a three-season sleeping bag rated to a sleep limit of 0°C (32°F), engineered for weight-conscious mountaineers and backpackers. At just 400g (14.1oz), it achieves its ultralight status 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 with Nikwax. The standout feature is the inner lining, which uses Thermo Ionic Lining Technology (TILT), a titanium coating applied to the fabric fibres that reflects body heat back to the sleeper, boosting warmth without adding weight or reducing breathability. Internal dimensions include a 215cm (86.5in) length, 70cm (27.5in) shoulder width, 52cm (20.5in) hip width, and 41cm (16.0in) foot width, sized for users up to 185cm (74.8in). Construction details include a trapezoidal baffle chamber design to prevent cold spots, a differential cut, an ergonomic hood and collar, an angled foot box, and a 1/8-length YKK 3-coil zip with a glow-in-the-dark puller. The bag is filled in Derbyshire, UK, and ships with a compression dry bag 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.
