For those not familiar with the EN rating, it is based on a standardized test for bags sold in the EU. Not sure if the test is mandatory, but it may be in some countries.

Thanks for including that link, Tom. I was being a bit lazy last night. Anyone wanting to check out the EN13537 ratings for Marmot bags can go to Marmot's European site:

The temperature rating you are looking for is the one between the yellow and the blue. To convert into Fahrenheit this site in handy:

I found it interesting that Marmot's stated rating for it's down bags is congruent with the independent ratings (the Hydrogen gets a EN 13537 rating of 31F) but is way off on the ratings for synthetic bags. Marmot says that the Pounder Plus is a 25F bag; the independent rating is 36F. The Pounder's rating is even worse. Marmot says it's a 40F bag:; the independent rating is 54F!
