Abstract: A removable, flexible, soft sided pocket secured to the external wall of a rigid, rectangular box shaped ice chest cooler. The pocket is configured in a width to height ratio similar to a side of a typical ice chest. The thickness of the pocket is small relative to its width and height. A zippered opening extends across the top of the pocket. The top and bottom edges of the pocket each incorporate attachment flaps that include two or more snaps that are positioned to align with snap bases on the side of the ice chest. The removable pocket may be snapped onto or removed from the sidewall of the ice chest leaving only the low profile snap bases permanently attached. The pocket may in kit form to allow for retrofitting an existing cooler with a pocket sized specifically for the cooler or ice chest.
