BasaranAvm 40 Lt Mega Size Thermal Bag with Thermos for Picnic Camping Beach Ice Cooler Cold and Hot Protective Bag

Hello, thanks to the aluminum insulation coating on the inside, it helps maintain the temperature of cold and hot products. When using ice, we recommend using the bag in an upright position (to prevent water leakage from the zipper section) to prevent melted water from leaking out. To keep it cold for longer, you can use an ice pack or freeze ice in plastic bottles.
