And cheaper. -the heavy duty zippers alone will cost a fortune and that's if you can find them. I bought my son's sleeping bag at the Army Surplus store. It was both warm and light weight. I had a couple moving van pads that I sewed together around the outside hem and then one seam across the center length and width. He had plenty of pad under him. He went camping in February and that was up in NW Ohio on the shore line of Lake Erie. Day time temps were only in the 20's -and lord only knows how cold the nights were or the wind chill factor.The Army bag was plenty warm .
