The Hampton lunch bag features PackIt's groundbreaking technology: a freezable non-toxic gel liner is integrated into the walls of the lunch bag, and the entire bag freezes. The design eliminates the need for separate ice packs. Frozen walls mean built-in cooling that chills food and drinks for hours! Simply flatten and place the entire bag in the freezer overnight. In the morning, the walls of the bag will be completely frozen and ready to pack. This tote-style cooler is so roomy you can carry larger containers (large meal or salad, a snack, and a 12-ounce drink) on the go. This soft-sided lunch bag is made with nontoxic gel and gel liner. Like all Packit products, the Hampton bag is made from PVC-free, BPA-free, phthalate, and lead-free (ul #b80321985, 12/5/2019) materials. Packit's freezable Hampton lunch bag measures 8.5” h, 10.5” w, and 7.75” d. Wipe thoroughly or hand wash the interior and spot a clean exterior; allow the bag to dry completely before freezing.
