All about this product



The Ascent 500 is a versatile Sleeping Bag with a comfortable, wide mummy fit. Filled with 500g of 650FP goose down and with ample space for wearing additional layers when needed, this lofty bag is ideal for two season use and spring conditions similar to those in the UK, New Zealand or Scandinavia.

The Ascent is built with a lightweight and durable, recycled Pertex Quantum outer fabric and recycled nylon lining. It has trapezoid shaped and boxwall baffles that stack neatly together, encouraging the hydrophobic duck down inside to loft fully and reducing the appearance of cold spots. The generous mummy fit with wide foot box provide a spacious feel for an easy night’s sleep, and the close-fitting neck baffle with three-quarter length zip keeps the heat in when the temperature drops.

The women’s specific shape is slightly shorter in length, narrower at the shoulders, and wider at the hips than the regular fit for improved efficiency. Practicalities are taken care of with an internal zipped stash pocket that easily fits a phone or a headlamp, a cotton storage sack and a compression stuff sack to ensure a manageable pack size and protection on the road. Exploring with a partner or want extra space? Pick up a left and a right zipped bag as the Ascent Regular and Long length versions have compatible zips so you can zip them together.
