January in Vermont

I purchased this bag November 2012 and have used it in every season camping in Vermont since then; the coldest January 2013 and spent two nights at - 5 F. Very comfortable and highly recommend.

Can anyone explain the difference between warmth ratings for this bag: European Norm Lower Comfort Rating 19 F, European Norm Comfort Rating 30 F and Degree 15 F ? Is it a fifteen degree bag or not?

Best Answer Responded on

The European ratings are a standardized rating system that is based on comfort levels of men and women at different temperatures. The Norm Comfort Rating is the maximum temperature that the bag is comfortable at for a standard male, the Lower limit rating is the lowest comfortable temperature for a standard male sleeping in a curled position.

In short, the ratings are different (15 degree stated vs 19 degree European Norm) in that the 15 degree isn't defined by a standardized system. This is the way that 75% of the bags sold in the US are rated, so if it says 15 degree, it'll be as close to a 15 degree bag as any other that is called such.

This bag has it all; Warmth, light weight, compressible. A solid synthetic bag. The addition of a full length zipper was a great improvement by MH, allows for more versatile use in warmer weather.

Are the zippers on both sides only 1/4 or 1/2 zips? The 2012 model has a zipper that goes all the way down. Is this is 2012 version?
