AO Coolers are the best soft-sided coolers in the industry. We were the first to introduce these innovative coolers 25 years ago. Our coolers are guaranteed to never leak or sweat because of our high quality TPU liner. The eco friendly TPU liner has a unique molecular structure that provides good compression set and high resilience, along with resistance to impacts, abrasions, tears, weather and more. 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. With our soft exterior, it won’t scratch up your gel coat or tear up any upholstery. This cooler will be the best cooler you will ever purchase.
