About this product
The Rab Ascent Sleeping Bag is a women's cold-weather bag rated to -11F (-23.33C), built for backpacking, winter camping, and mountaineering. Its wide mummy shape offers more room to move than a traditional mummy cut while retaining heat effectively, aided by sidewall baffles that maintain consistent loft for side sleepers. L.O.F.T baffles reduce down migration and improve packability, while the anatomical hood, 3D neck collar, and shaped footbox work together to seal in warmth at key heat-loss points. The 650-fill-power RDS-certified European duck down carries a Grangers PFC-free hydrophobic finish to preserve loft in damp conditions. The 20D Pertex Quantum face fabric (100% nylon ripstop with a PFC-free DWR finish) pairs with a 20D recycled nylon lining for a balance of durability and low weight. A 3/4-length zipper with anti-snag construction, a zippered side vent, a full-length draft tube, and one internal zippered pocket complete the feature set. Packed weight is 1,080g, and the bag comes in regular and long lengths in Dark Bluebird/Bluebird colorway.

What people are saying
Reviewers consistently praise the Rab Ascent Women's -11F bag for its generous, women-specific mummy fit that is noticeably wider at the hips than competing bags, making it comfortable for side sleepers and those who like to curl up. The durable Pertex Quantum shell, Nikwax hydrophobic down treatment, and thoughtful details (glow-in-the-dark zip pull, neck baffle, internal stash pocket) earn repeated compliments. The bag is widely considered strong value for a cold-weather down bag at its price point. The most common criticism is that the roomy cut can leave dead air space that reduces warmth efficiency in the coldest conditions, and some cold sleepers report feeling chilly near the rated limit. Its weight is also noted as a drawback for those prioritizing ultralight packing.
