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 who seek real warmth, comfort, and reliability in cold winter conditions. Within the Rab range, Ascent represents the balance between thermal performance and comfort, moving away from narrow alpine bags to offer a more natural and less restrictive sleeping experience.

Real Technical Performance

With a comfort temperature of -10°C and a limit of -18°C, this bag is designed for winter trekking, cold mountain conditions, and bivouacking in demanding environments. Its greater internal 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 along with L.O.F.T.™ construction helps maintain stable loft throughout the night, reducing cold spots and improving thermal efficiency.
