[pct-l] Sleeping Bag Ratings

[patti kulesz]

actually the more layers u wear the colder u are from what I was told b/c the bag uses ur body heat to warm up. So if ur wearing more layers then it's that much more work for the heat to get to ur bag...just what I was told by several bag reps that's all

Also depends on where you are in the world, what "standards" are used
for 
testing, and a whole bunch of other vaiables. A couple of good articles :

I'd bring along a bag of feathers from PH Designs, and on cold nights, wear
a 
few more layers.
