The new Women's Ascent -12°C Sleeping Bag from Rab offers warmth and comfort during the cold night under the stars. This sleeping bag is filled with 650FP European duck down with Grangers fluorocarbon-free hydrophobic finish, which traps air efficiently, creating clusters that retain body heat. 

The mummy shape provides a wide sleeping space to move around in, paired with an anatomically shaped foot box for a relaxed sleeping posture. The adjustable hood means you can control how you trap heat at the top of the sleeping bag, adjusting to your preferred needs. This sleeping bag comes with a handy stuff sack so you can condense the sleeping bag down for carrying in your rucksack, as well as a zipped storage sack for keeping your sleeping bag thriving at home.
