About this product

The Rab Ascent 0F is a women's down sleeping bag designed for cold-weather backpacking and mountain trekking, rated to 0 degrees Fahrenheit (approximately -18 degrees Celsius). Its wide mummy shape provides freedom of movement and comfort without creating cold spots, while an anatomical hood, neck collar, and full-length draft tube work together to seal in warmth. The insulation is 650-fill-power RDS-certified European duck down treated with a Grangers PFC-free hydrophobic finish, helping it retain loft in damp conditions. L.O.F.T baffles minimize down migration and aid packability, and sidewall baffles add loft for side sleepers. The shell is 20D Pertex Quantum nylon ripstop with a PFC-free DWR finish, while the lining uses 20D 100% recycled nylon. A 3/4-length zipper with zippered side venting, one internal zippered pocket, and a drawcord-adjustable stuff sack round out the feature set. Packed weight is 454 grams, and the bag is available in regular and long lengths.

What people are saying

Reviewers consistently praise the Rab Ascent 0F Women's sleeping bag for its impressive warmth, with users reporting comfort in sub-zero conditions even when wearing minimal layers. The wide mummy shape and angled foot box earn repeated compliments for comfort and roominess compared to standard mummy cuts. The Nikwax hydrophobic down treatment, trapezoidal boxwall baffles, and durable recycled Pertex Quantum shell are highlighted as standout features. The most common criticism is the bag's bulk and weight (around 52 oz), making it less ideal for ultralight backpacking. A few users note that cold sleepers may still feel chilly without a quality sleeping pad underneath, suggesting the temperature rating runs slightly optimistic for some.
