AO’s Hybrid Cooler is the first of its kind! The rigid soft cooler is a hybrid between a hard cooler and a soft cooler. The insulation along with the thick outer material makes the cooler perform like a hard cooler, but with the lightness of a soft cooler. The welded, eco-friendly TPU material and molded EVA bottom make it rugged and durable. It also has durable, water-resistant YKK zippers for top lid access.
