[This review was collected as part of a promotion.] Awesome sleeping bag,very warm and comfortable! Got caught in 1 1/2" of rain then 10" of snow for 2 weeks,I was surprised how warm i stayed all night at 10 degrees and my toes have always been a problem before,but I just had regular socks on and my feet were warm!!!
This sleeping bag does not keep me warm below 20 deg F. I have used it for 3 years in late October for elk hunts, and its fine if temps stay above 20, but nights in the teens I am very cold even with multiple layers of clothing on.
