Limit rating
The limit rating is one of the temperature figures on a sleeping bag label. It is the lowest temperature at which someone who sleeps warm should get through the night curled up in the bag, and it is usually a lower number than the comfort rating.
Where you'll see it
It sits on sleeping bag labels and product pages, beside the comfort and extreme ratings. Some shops lead with it because it is the lower number. Use it to understand the bag, but shop by the comfort rating, and check the maker's page to see how all three figures were worked out.
What to check
- Which figure is labelled limit, and which is labelled comfort.
- Whether the maker names the standard behind its figures, or gives only a headline number.
- Whether the rating assumes a particular mat, liner or set of clothing.
- Whether the comfort rating sits at or below the forecast low for your site.
