What independent testers found
What owners report
Owners commonly report warmth in cool conditions, a roomy fit and good value; several find it bulky to pack. The review pool does not establish durability.
Limits and cautions
- The rating uses the 2017 edition of the standard, not 2022. The maker does not state a maximum user height or the tested specimen size.
- The comfort figure is an adult laboratory rating, not a promise for every person, and not for children or infants.
- Use insulation underneath; a cold floor draws heat away.
