What this ranking does not cover#
This ranking compares published weight, list price and the temperature rating each maker states. It does not cover fit, draft control, how warm you sleep, or how the insulation holds up over years.
Makers rate bags differently: some publish an ISO or EN comfort rating, others a lower limit. Two bags with the same stated rating can sleep differently, so check which rating the maker gives.
For 3 models here, among them the Therm-a-Rest Vesper 20°F/-6°C Down Quilt, the Therm-a-Rest Corus 20°F/-6°C Down Quilt and the Therm-a-Rest Boost 650 20°F/-6°C Sleeping Bag, the maker publishes a weight for each size and none for the model; each is ranked at the weight of its lightest size.
Each bag is ranked at one temperature rating, the one recorded with its published weight. Some makers sell the same bag in several ratings; a version at this rating that is not on record is not ranked here.
Questions people ask#
