How to read the numbers

Sleeping bag comfort vs limit temperature, and how to chooseCAMP GEAR NOTESleeping bags by the numbers2026.10.18Product image: Rakuten IchibaProducts in the image (Rakuten Ichiba): Sea to Summit Spark -1C / mont-bell Seamless Down Hugger 800 #3 / NANGA Aurora Tex Light 480DX / NANGA Aurora Tex Light 630DXSleeping bag comfort vs limit temperature, and how to chooseAcross 15 official listings, the gap is 4–8°C. Choose a sleeping bag by its comfort temperature. The difference between comfort and limit is whether you can sleep in a relaxed position, or whether a cold-tolerant person can sleep curled up. In the 15 bags that list both, the gap is 4–8°C. Buy by the limit and you end up one model colder. I also chose picks for lows of 5°C, 0°C and −5°C.How to read the numbers / Oct 18, 2026
