[pct-l] Sleeping Bag Ratings

[Hannah Brewster]

Sleeping bag temperature ratings are the lowest temperature at which  
you will be comfortable assuming you are INSIDE a tent and ON TOP OF a  
crash pad.  Some companies list temperature ratings from EN 13537 test  
which they uses in Europe.  They will list the comfort range, lower  
limit, and extreme limit for temperatures.  I know Marmot tests their  
bags this way and they have a pretty good explanation of it on their  
web-site.
