AO coolers are the best soft-sided coolers in the industry. Don’t be fooled by imitation coolers. AO Coolers are guaranteed to never leak or sweat because of the high quality vinyl liner, the same material used to make waterbeds and above ground pools. The inner insulation is three-quarters of an inch thick, high-density, closed cell foam. The combination creates a cooler that will hold ice for 24 hours in 120-degree heat and with a soft exterior, it won’t scratch up your gel coat or tear up any upholstery. AO guarantees the coolers for life. Tested, used, and sold by many of the performance boating industries and top manufacturers. This cooler will be the best cooler you will ever purchase.
