Cramer Flex-I-ColdTM packs are a staple item in almost every gym, team kit, and coach's office. These gel packs are sealed in a puncture-resistant plastic bag that can withstand multiple uses. These packs remain pliable at temperatures above -4 degrees Fahrenheit, making them an excellent item for quickly icing down an injured wrist or ankle. The gel can also be warmed and used to treat musculoskeletal injuries, reduce stiffness, and promote healing by increasing blood flow and circulation. Two sizes to choose from.
