Although comfort ratings for quilts are very subjective, I think it's worth to share the values we're currently working with: Our temperature ratings for quilts are roughly equivalent to the limit comfort temperatures (*) of the EN rating standard. That’s the temperature you commonly see as the EN rating of a sleeping bag. It’s defined as the temperature at which a standard man can sleep for 8 hours without waking. There is a real lack for women UL sleeping bags, not to say quilts. So we've been working for a while on this and have reached the previous values. How do you feel with these values? I have a special interest in women's feedback. (*) To make things clear, those are not EN temperature ratings. The EN standard (usually cited as EN 13537 but cancelled by EN 23537 since 2017) is designed to test traditional sleeping bags, not open quilts. As a consequence, the results of testing quilts are not really useful and the margin of confidence depends a lot on quilt design. This is the reason no quilt manufacturer provides real EN ratings. What’s worse, some quilt manufacturers provide temperature ratings that seems to be based on the EN standard, but that’s not really true (none of them provide lab certificates!). Even some sleeping bag manufacturers are not clear (honest?) in this regard. Take into account that testing a single bag has a cost over 2000 €.
