Thank you very much for viewing. Excellent cooling power thanks to the three-layer structure!! You can carry cold items while keeping them cold. It is designed to accommodate the separately sold Enecharge, and the synergistic effect with Enecharge achieves amazing cooling and heat retention!! When combined with the separately sold Enecharge, it can also be used as a chair. The top lid has a thick fabric and a structure that considers comfort (vertical load test cleared approximately 200kg). Holds up to 8 x 350ml aluminum cans.
