The Ascent 500 is a versatile bag with a comfortable, wide mummy fit. Filled with 500g of 650FP goose down and with space for wearing additional layers if needed, this bag can be used in cool temperatures. 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, boxwall baffles that stack neatly together, encouraging the hydrophobic duck down inside to loft fully 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 generous mummy fit with wide foot box provide a spacious feel for an easy night’s sleep, and the close-fitting neck baffle keeps the heat in when the temperature drops. It has a ¾ length main zip with a down filled baffle to keep out the draught. 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 and you can zip them together.


  • Pertex® Quantum is a soft, lightweight, windproof fabric that encourages insulation to fully loft. Highly packable and protective, it's ideal for mountain activities.

  • The Ascent series is designed for wild campers, adventure backpackers, and draughty Scottish bothies. Combining clever construction to optimise warmth with a generous fit, it ensures a comfortable night’s sleep for the weary mountain explorer.
  • RDS Certified Down: The Responsible Down Standard independently certifies down against animal welfare requirements and tracks it from the source to the final product.

  • Fluorocarbon-Free DWR: A durable water repellent coating made without harmful fluorocarbons, that encourages water to bead and roll off the garment, keeping you dry. Find out more about why we're cutting out fluorocarbons from our gear.
