Temperature Rating Tip
Get a bag rated 10-15°F below your expected low for a safety margin. Most manufacturers rate conservatively — a '20°F bag' might keep you comfortable at 25-30°F.

Understanding Temperature Ratings
ISO testing gives a bag two numbers: a comfort rating and a lower limit rating. Here's the honest truth: bags are usually marketed on the limit number, which is closer to "you will survive the night" than "you will sleep well." So a bag sold as a "20°F bag" often keeps an average sleeper genuinely comfortable only around 25-30°F.
Get a bag rated 10-15°F below your expected low for safety margin.
Cold Weather Tips
Even the best sleeping bag won't help if you don't:
- Eat a big dinner - Digestion generates heat
- Stay dry - Wet clothes = cold night
- Layer up - Wear dry base layers to bed
- Use a sleeping pad - Ground steals 80% of your body heat
- Put clothes in your bag - Cold boots in your bag = warm feet (eventually)
