Sleeping Bags & Quilts
A temperature rating is a manufacturer claim unless the bag is explicitly tested to ISO 23537, so compare the basis of the rating as well as the number. Higher down fill power means more warmth per ounce, while quilts save weight by relying on the sleeping pad beneath you and mummy bags enclose the body to limit drafts.
