I sleep pretty cold. I've got an EE 20 degree quilt which is great for me but only up until about freezing. So I'm looking for something comfy and fairly light which will take me down into the teens. Not heavy-duty winter backpacking. I'm 6'0" and about 165-70. I can get it in a Labor Day sale for about $350, and a $600 bag is out of my range. I rarely make a gear purchase this big, so I'm getting nervous. Any reason I shouldn't go ahead?
Thanks for any thoughts.
