The Camper Flannel Outfitter sleeping bag is a great choice for rental programs. It features a #10 zipper, so it will last time and time again through repeated, rugged use. The outer is a durable Ripstop that looks as good as it feels. The 100% cotton flannel lining provides an extra soft feel when you are sleeping under the stars in the wilderness. Two Camper Flannel bags can be zipped together to create a double bag.
