Rab Ascent 700 -9 Sleeping Bag (1290 Grams)

A warm, 650FP duck down sleeping bag with a recycled, wind resistant Pertex Quantum outer. Designed with a comfortable wide shape, it’s ideal for those buying their first down sleeping bag for use in cold conditions.

The Ascent 700 is a warm bag with a comfortable, wide mummy fit. Filled with 700g of 650FP goose down and with space for wearing additional layers if needed, this bag can be used in cold temperatures. Ideal for three 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 downs loft and warmth.

The generous mummy fit with wide foot box provide a spacious feel for an easy nights sleep, and the close-fitting neck baffle keeps the heat in when the temperature drops. It has a 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 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.
