Women's Ascent Pro 800 Down Sleeping Bag (-15C)
Warm and spacious, the Women’s Ascent Pro has much of the same construction as our most technical bags but with a wider, comfier fit, and women’s specific shape. Perfect for those investing in their first down bag for cold, winter conditions, it’s built with water resistant Pertex® Quantum Pro and filled with 650FP duck down.

- Mountaineering
Warm and protective, the Ascent Pro 800 is ideal for Scottish and Scandinavian winter conditions. It has a generous wide fit, ensuring a comfortable night’s sleep for the weary mountain explorer. The women’s specific version is shorter in length with a narrower shoulder and wider hip space than the regular version. Filled with 800g of 650FP duck down, it is a very warm sleeping bag, with space to wear extra, bulkier layers inside if using in seriously cold temperatures.
With Pertex® Quantum Pro wind and water resistant outer and hydrophobic duck down, it copes well with wind, condensation, and damp conditions, ideal for snow holing or an exposed bivi ledge. Warm enough to deal with plummeting temperatures it’s a great all-round adventure, winter sleeping bag. Built with trapezoid shaped, boxwall baffles that stack neatly together, the down inside is encouraged to fully loft, maximising insulation and reducing the appearance of cold spots. Hand-filled in the UK, all our down bags benefit from never having had their down compressed before use, maintaining the down’s loft and warmth.
The Ascent Pro has a ¾ length main zip with a down filled internal baffle and 3D shaped neck baffle, both designed to limit any heat escaping. There’s a zipped pocket inside, ideal for stashing your headlamp within easy reach, and with its angled foot box you can be sure of comfy position to sleep. Exploring with a partner or want extra space? Pick up a left and a right zipped bag and you can zip them together.
