sleeping bag

Great bags and bivy all clean and ready to go.

Great But Not Great

Quality and condition of the materials were great. Your service was great. The bags are indeed warm, even on cold nights. I've already tested them. The bags are a bit small though. I am somewhat big but not real big (6' 1" 225lbs.).....and I just feel very cramped in it......especially the intermediate bag......which is a very nice bag actually, it's just too small! This made me a bit disappointed. Fortunately I'm not using this Mod. sleep system for any missions or expeditions! I'll make it work okay for camping!
