Rab Ascent Sleeping Bag: 20F Down - Women's

What Our Gearhead® Experts Are Saying:"I like the Ascent 20F Sleeping Bag for shoulder-season trips where nights are cool but not brutal. The wide mummy fit is noticeably more comfortable than most bags in this temp range, and the sidewall baffles keep warmth even if you move around. It’s a great everyday bag for regular backpacking."We reach for the Ascent 20F Sleeping Bag when trips span spring, summer, and fall and conditions can shift overnight. Built for trekking and backpacking in cool mountain environments, it delivers dependable warmth with a roomy shape that helps us sleep comfortably night after night. The Ascent is constructed with L. O. F. T™ baffle technology and sidewall baffles to reduce down migration and maintain consistent loft. A wide mummy profile, anatomically shaped footbox, and 3D neck collar improve comfort—especially for side sleepers—while practical features like the arm access vent and smooth YKK® zippers make it easy to manage changing temperatures. Filled with hydrophobic 650FP European duck down and wrapped in a lightweight Pertex® Quantum shell, it balances warmth, durability, and packability for regular use.
