When shopping on a hot day, I'm afraid that the food will be damaged. In such a case, we recommend a cool bag that folds the gusset area for compact storage. Thermos's “cool shopping bag 25L RER-025” is a large-capacity size that holds 8 2L PET bottles. Moreover, it has a 4-layer heat insulation structure, which has a high cooling effect and a large opening, making it easy to use. .
