The Cruiser 15qt. rotomolded white cooler from Mammoth Coolers is perfect for a trip to the beach or the park. It holds a 12-pack of cans and keeps your contents cool even if you leave them in a hot car. The insulated walls support ice retention for up to two days. The lid is constructed with a freezer-grade gasket made of thick rubber that seals against the rim to prevent any air flow.
