A universal waterproof cooler with buoyancy assistance, this product ensures your contents stay dry. Its IPX8 airtight seal is achieved through a magnetic auto-sealing double lock closure and is tested to 100 feet deep. Two Fidlock magnetic buckles reinforce the seal, making it air, water, and gas-tight. The durable TPU shell and cut-proof NBR insulated inner lining help keep ice for over 24 hours. This floating cooler accommodates 12 cans (without ice) or a lunch. This multi purpose bag weighs 2.5 lbs empty, measuring 13" H x 7" W x 17" L (top) / 13" L (base), and includes two external water-resistant pockets, multiple hand grabs, and a removable padded shoulder strap.
