Warm and protective, the Ascent Pro 600 has a generous wide fit, ensuring a comfortable night’s sleep for the weary mountain explorer. Filled with 600g of 650FP duck down, it is a warm sleeping bag, with space to wear extra, bulkier layers inside if the temperature suddenly drops.

With Pertex® Quantum Pro wind and water-resistant outer and hydrophobic duck down, it copes well with wind, condensation, and damp conditions, ideal for an exposed bivi ledge. Warm enough to deal with plummeting temperatures it’s a great all-around adventure, a three-season sleeping bag. Built with trapezoid-shaped, box wall baffles that stack neatly together, the down inside is encouraged to fully loft, maximizing insulation and reducing the appearance of cold spots. Hand-filled in the UK, all our own bags benefit from never having had their own 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 a comfy position to sleep in. Exploring with a partner or want extra space? Pick up a left and a right-zipped bag and you can zip them together.
