This soft sided cooler was designed not only to fit perfectly in the storage rack behind the seat of a golf cart. Aside from having our White Wing styling on the exterior and 3/4 inch closed cell foam insulation, we wanted to make our product set itself apart from most other soft-side coolers in that it is 100%, without fail, LEAKPROOF. We sourced the most rugged and durable liner we could find, 22 oz. heavy duty Vinyl to be specific, and had all seams RF (radio frequency) welded with a 1/2″ bead width. All this to say, it absolutely, positively, WILL NOT LEAK.
