I am looking at Slumberjack Sleeping Bags for spring time camping and I ran aross the Slumberjack Minaret Regular Right Sleeping Bag. It has the easy access Draw cords with barrel locks on the collar. It has weather sewn at the base of the zipper to pervent heat loss and has the vented footbox that zips open to give you more room. The sleeping bag adds comfort in a wide range of temperature. Look at Acme Sleeping Bags.
