Mythic Down Sleeping Bag (-6°C)

The Rab Mythic Down Sleeping Bag (-6°C) is built for mountain users who count every gram but still need dependable warmth when conditions turn cool. It’s an ultralight, low-bulk bag aimed at fastpacking, alpinism, and other trips where pack space and carried weight matter as much as overnight comfort.

Rab has put its focus here exactly where it counts. The bag uses 900FP European goose down for high warmth at low weight, with L.O.F.T 3D™ helix-shaped baffles that help stop the down from shifting and keep insulation evenly distributed. A heat-reflective TILT lining helps hold warmth around the body without adding meaningful weight, while sidewall baffles reduce cold spots and keep you from lying on a seam if you sleep on your side. Finished with Pertex® Quantum ripstop and hand-filled in the UK so the down has never been compressed before use, it’s a stripped-back mountain bag that stays honest about what it’s for: moving fast and sleeping warm.
