About this product

The Rab Ascent 10F Down Sleeping Bag is designed for cold-weather trekking and backpacking, with a wide mummy shape that provides more room than a traditional mummy cut for improved comfort and freedom of movement. The shell is made from Pertex Quantum fabric, which balances low weight with durability, while the fill consists of 650-fill-power hydrophobic European duck down that resists moisture absorption to maintain warmth in damp conditions. L.O.F.T baffles minimize down migration throughout the bag and contribute to better packability, and sidewall baffles increase overall loft while supporting side sleepers. Heat retention is further addressed through an anatomical hood, a neck collar that seals in warmth around the shoulders, and a shaped footbox that conforms to natural foot position. This combination of construction details makes the Ascent a practical choice for backpackers who need reliable cold-weather performance without excessive weight.

What people are saying

Reviewers consistently praise the Rab Ascent 10F for its reliable warmth, spacious wide mummy fit, and durable Pertex Quantum shell that resists wind and moisture. The hydrophobic duck down treatment earns repeated approval for maintaining loft in damp conditions, and the roomy cut is frequently highlighted as a comfort advantage for side and stomach sleepers. The bag is widely regarded as strong value for cold-weather trekking and backpacking. The most common criticism is that 650-fill duck down delivers a noticeably worse warmth-to-weight ratio than higher-fill goose down alternatives, making the bag heavier and bulkier than comparably rated competitors. Some users note the temperature rating can feel optimistic in practice, and the extra interior space can create cold spots at the lower end of its rated range unless layered appropriately.
