Thread: Kuiu sleeping bag

I'm not familiar with either your current bag or the Kuiu so can't help there. You didn't mention if you were wearing anything on your head. A good beanie does wonders. If you feel the cold then I'd look towards a hooded bag and a down pillow.
Try and get warm before you hop into bag, remember that all a good bag does it hold your generated body heat, not create it. Thermarest make some truely awesome bags that attach to your neoair and create a very efficient sleeping system.
