Packits are the original foldable, freezable, permanent, lunch bags. Packit personal coolers are perfect for school, work, the field or anywhere else you plan to snack. Thanks to their patented eco-gel liner, Packits keep your contents cooler, longer. No need for bulky ice packs. No need for ice that quickly melts. Simply store a folded, compact Packit in your freezer until you're ready to go. The patented eco-gel cooling material is permanently sealed in the lining and will keep food and drink cool up to 10 hours. Packets are PVC-free, lead-free and non-toxic. Packit personal coolers measure 8" x 10" x 5" and only 8" x 5" x 2" when they're folded.
