PSI Flex-Gel Cold Packs - Reusable Gel Ice Packs
The outer covering is pretty thin. Have to keep it carefully in the freezer to avoid puncture. Gel gets very frozen and hard, have to let it sit out before wrapping extremity to mold it easily. Doubt if it will last 6 months with kids and teenagers using it. Got what I paid for, better than a leaky bag of ice.
