Cumulus bag ratings

I always ignore the ratings. Instead I compare the rest of the specs to a bag from Western Mountaineering.

well it seems legit… see this blog

but yes compared to WM/FF offerings the price seems "too good to bee true"

if those bags are en-rated and that is an en-rating then yes it should be fairly accurate for the "average" euro bum …

ask them if it is en-rated and ask for the full rating set …

I know a few folk who use Cumulus bags and are happy with them. Most of their bags are differential fill though (more down on top), so that might make a difference if you aren't a back sleeper.
