The best sleeping bag I have ever owned is 35+ years old and to this day keeps me so warm that I get HOT in it and generally sleep with the zipper unzipped and one leg hanging out (oops, sharing personal info) and it never gets so wet that it doesn't keep me dry plus any water shakes out easily. I used this sleeping bag this last summer on my Mt. Whitney trek. I stayed warm every night even when the wind was howling. My friends didn't stay as warm in their sleeping bags. I purchased my bag a Back Country in Buena Park when I was 19. The fill in my bag is polar guard, it's awesome. When I bought my bag, Back Country made all their products on sight. I also bought my first backpack from them. I carried that backpack all over Europe and on many trails in the U.S.A. I wonder if Back Country is still in business???
So Cal Girl, my friends bought the bags that are one sided and have a pocket to slide their pad into and I don't think they're very happy with their bags, in fact, one of my friends borrowed one of my two sided REI bags for our MW trek last summer. When I sleep, I roll over and over all night long, I'm a wild sleeper (due to great dreams), so I want every side of my bag to be cushioned. My friends say I can sleep anywhere,I love my sleep. zzzzzzz
