Rab Ascent Sleeping Bag: -11F Down - Women's Dark Bluebird/Bluebird, Reg/Left Zip

What Our Gearhead(R) Experts Are Saying:"I recommend the Ascent for cold sleepers or trips where temps can really drop. The wide mummy cut gives you room to move without cold spots, and the sidewall baffles keep loft consistent all night. It's warm, dependable, and feels built for real winter use rather than shaving grams."We rely on the Ascent Sleeping Bag when winter trips push into truly cold territory. Designed for backpacking and mountain nights where warmth is non-negotiable, it balances serious insulation with a comfortable, livable shape that makes long nights more restful. Built with L. O. F. T(TM) baffle technology and sidewall construction, the Ascent maximizes down loft while minimizing migration, helping maintain warmth through repeated use. The wide mummy profile, anatomically shaped footbox, and 3D neck collar improve sleeping comfort, especially for side sleepers. A 650FP hydrophobic European duck down fill, Pertex(R) Quantum shell, and thoughtful details like an arm access vent and anti-snag zips round out a sleeping bag designed for reliable cold-weather protection.
