"kbmccoll" - Review of Marmot Helium Sleeping Bag: 15 Degree Down
This is an excellent bag for the money. It reaches its temperature rating easily if used in a bivy bag. That way you can use the regular Helium and not get wet. We slept under a fly,in bivy sacks on shorty thermarests down to minus 10 C. No problem. I love the way it compresses. This Fall we'll try it while elk hunting when pack space is at a premium. My scale might be wrong but I think it weighs about 1.5 kilos but that is still better than any other bag I have tried. I find it roomy too (I'm 5'11" and 170 lbs)
Durability remains to be seen but I think it's the answer for me.
