The Rab Women's Ascent Down Sleeping Bag is perfect if you are looking for a sleeping bag that prioritises warmth, comfort, and practicality. That will give you an easy night’s rest in the wild, without compromising on weight or pack size. This ultra-warm, robust down-filled bag offers the reliable protection you need in cold conditions. Armed with 650FP duck down, a spacious, wide mummy shape, windproof Pertex® Quantum fabric, and a clever baffle construction that maximises warmth for weight, it's perfect for backpacking and mountain treks.

Hand-filled in the UK, all our down bags benefit from never having had their down compressed before use, preserving their loft and warmth.

Rab Women's Ascent Down Sleeping Bag Features:

L.O.F.T™ construction uses alternating wide and narrow baffles to achieve great warmth for weight.

Sleep comfortably on your side thanks to the sidewall baffles, which reduce cold spots and ensure you’re not lying on a seam.

A second shorter zip with integrated snap closure allows you to use your arms while retaining heat in your sleeping bag, ideal for cooking in the cold.

Cinch in the hood to seal in the heat, while the synthetic insulated collar sits snugly around your neck.

Sleep in a relaxed, comfortable position thanks to the roomy, anatomically shaped foot box.

Keep valuables and essentials close at hand with a zipped internal stash pocket.

Wide mummy fit gives space for extra layers when night temperatures plummet.

Internal cordlocks positioned below your collarbone for greater side sleeping comfort.

Two-way YKK® ¾ length main zip with synthetic-filled baffle.

YKK® anti-snag zip insert and anti-snag internal zip guard.

Drawcord stuff sack included.

Zipped storage sack with water-resistant base for home storage.

Hand-filled in Derbyshire, UK.
