Rab Mythic 200 Down Sleeping Bag (1C)

The Mythic range has been crafted with a singular purpose—shaving off every unnecessary gram. The Mythic 200 is a remarkably lightweight sleeping bag tailored for spring and summer conditions. Built for high mountain environments, it is an excellent choice for extended Alpine adventures, multi-day climbs, long treks, or minimalist bikepacking excursions.

With a total weight of just 515g, it includes 200g of ultra-high lofting 900 fill power goose down. Its distinctive chevron-style baffle construction keeps the down evenly distributed, enhancing core warmth while reducing fabric use compared to conventional horizontal baffles. The outer shell is constructed from Rab’s own recycled Atmos™ fabric, which resists both wind and moisture. Designed with a close-fitting mummy shape to cut down on bulk, it features streamlined zips and pullers, and comes with a roll-top waterproof compression sack to guard against the elements and ensure a compact carry on the move.

The trapezoidal boxwall baffle system allows the down to loft to its full potential, effectively removing cold spots and boosting thermal efficiency. An adjustable neck baffle and an internal baffle running the length of the zip are both designed to seal in warmth. Each bag is hand-filled in the UK, and because the down is never compressed beforehand, it retains its natural loft and insulating performance from the moment it is used.
