Emperor 80 cooler From cracked corners to caved-in lids, ordinary coolers can’t handle a life of adventure. The Pure Outdoor Emperor coolers are anything but ordinary and are built to take the abuse that comes with the way you play. Built with extra-thick walls, the main body and lid are each manufactured using pressure-injected, commercial-grade polyurethane foam in a stress-free, low-pressure rotomold. Each cooler features slots on each side for tie-down straps to keep your cooler from sliding around in the back of your truck or boat.
