The Ascent -24C / -11F by Rab is a sleeping bag specifically designed for women, offering unmatched cold protection thanks to its 650FP European duck down fill. The L.O.F.T™ technology minimizes down migration, ensuring optimal heat retention. Its mummy shape design, with a spacious foot area and side baffles, provides increased comfort for side sleepers. Additionally, the anatomical hood with drawcord maximizes heat retention.
For added comfort, the sleeping bag features a 3D collar with recycled Stratus™ insulation and a three-quarter length YKK® two-way zipper, complemented by a synthetic-filled draft tube to prevent drafts. Arm access via a YKK® zipped vent with integrated snap closure allows for heat retention when performing tasks inside the tent. The internal and external storage pockets, along with the compression sack and waterproof storage bag, ensure optimal organization.
Ideal for mountain hikes and trekking, the Ascent -24C / -11F offers the perfect combination of warmth and comfort, even in the most demanding conditions.
