Rab Ascent -18°C Womens Sleeping Bag | Down Winter Trekking Sleeping Bag

Description

The Rab Ascent -18°C Women's is a down sleeping bag designed specifically for women looking for real warmth, comfort, and reliability in cold winter conditions. Within the Rab range, the Ascent represents the balance between thermal performance and comfort, moving away from narrow alpine bags to offer a more natural and less restrictive rest experience.

Real technical performance

With a comfort temperature of -10°C and a limit of -18°C, this bag is oriented toward winter trekking, cold mountains, and bivouacs in demanding conditions. Its larger interior volume improves actual rest, allowing for more freedom of movement and the ability to add layers if necessary.

The use of 650FP European duck down with a hydrophobic treatment, combined with L.O.F.T.™ construction, keeps the loft stable throughout the night, reducing cold spots and improving thermal efficiency.
