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.
