Rab Women's Ascent 700 Down Sleeping Bag (-9C)

The Ascent 700 is a warm and spacious sleeping bag designed with a generous mummy shape for added comfort. Filled with 700g of 650FP duck down, it provides excellent insulation while allowing room for additional layers if required, making it well-suited for cold conditions. Ideal for three-season use, it is particularly suited to spring climates found in regions such as the UK, New Zealand, and Scandinavia.

Designed specifically for women, this version of the Ascent sleeping bag features a slightly shorter length, a narrower fit at the shoulders, and a wider shape at the hips for enhanced thermal efficiency. Constructed with a lightweight yet durable recycled Pertex® Quantum outer fabric and a recycled nylon lining, it offers both sustainability and performance. The trapezoidal boxwall baffle construction ensures that the hydrophobic duck down lofts fully, minimising cold spots and maximising warmth. Hand-filled in the UK, all down sleeping bags in this range retain their loft from the outset, as the down is never compressed before use, ensuring optimal insulation.

The spacious mummy design, combined with a wide footbox, provides a comfortable sleeping experience, while a snug-fitting neck baffle helps to retain warmth on colder nights. A ¾ length main zip, complete with a down-filled baffle, effectively blocks out draughts.

Practical features include an internal zipped stash pocket for securing essentials such as a phone or headlamp, a cotton storage sack for long-term care, and a compression stuff sack to reduce pack size for travel. For those adventuring with a partner or seeking extra space, a left-zipped and right-zipped version can be paired together.
