RabAscent -18C / 0F - Men's sleeping bag

The Ascent -18C Men's Sleeping Bag from Rab is your reliable ally for mountain adventures. Designed to provide optimal comfort, it features a wide mummy shape, generous foot space, and side baffles that increase the down volume. The L.O.F.T™ baffle technology minimizes down migration, enhancing heat retention and the bag's compactness. Made with a 20D Pertex® Quantum ripstop nylon fabric and a fluorocarbon-free DWR finish, this bag is both durable and environmentally friendly.

Every aspect of the Ascent -18C Men's Sleeping Bag is designed to maximize your comfort. The anatomically designed hood with drawcord and the 3D-shaped collar with recycled Stratus™ insulation wrap you in warmth. The main YKK® two-way zipper, 3/4 length, is accompanied by a snag-free protection, while internal zippered pockets offer convenient storage space. The bag also features arm openings with integrated snap closure, ideal for tasks inside the tent.
