Down warmth that packs small

If you judge a bag by how much warmth it packs into how little space, down is hard to beat. This mummy bag is filled with white duck down, which lofts up to trap warm air and then compresses down small in the included sack, from as little as 16 by 20cm at the summer weight. Eleven fill weights run from 400g for mild nights up to 3000g for deep cold, so you match the bag to the trip rather than carrying more than you need. The water-repellent 320T nylon shell sheds moisture and dries quickly.

Read the rating honestly

The maker rates the heaviest version to an extreme figure of around -40C. Treat that extreme number as a survival limit, not a comfort level, and pick a weight with a bit of headroom over your coldest expected night. Inside, 3D baffles keep the down from shifting so you do not wake up with cold gaps, while the YKK dual-sided zip, Velcro guards and draft tube stop heat leaking along the seam. It comes in Green, Green Camouflage and Khaki Camouflage.
