Slumberjack Go N Grow youth / kids sleeping bag.  Adjustable zippered area near the bottom to extend the length of the sleeping bag.  This will be great for a younger kid to grow with as they grow.  Note this one is marked as vintage, because this is one of the older models that was made better, with nylon shell and nylon lining (the newer design of this model uses polyester instead of nylon).  This bag weighs approx. 2 lbs. and 13 oz. without shipping packaging.
