It has zippers on all 4 corners and in the center of one side. It has 2 handles what I figured to be the inside. Has 2 hooks on each end for what looks like duffle bag straps. Also has 4 small straps on the sides and 2 small pockets on the side with the zipper. I got it inside of a pack that I found at a yard sale. It's big enough to fit a 100 liter cooler inside
