• NEW DESIGN: Horizontal cells flex naturally as you bend and stretch
• Nontoxic, biobased cooling material maintains a comfortable 59° F for 2.5 hours
• Packs fit Glacier Tek sports, concealable, original and classic cooling vests
• Set consists of 4 large packs and 4 small packs -- use only as many packs as you need to stay cool

For added comfort, Glacier Tek adult cooling packs now feature horizontal cells that conform to your torso as you bend and stretch. The packs come in two sizes: 10.3 ounces and 7 ounces. For maximum cooling, insert a large and a small cooling pack into each inside pocket of your vest. For less demanding conditions, such as office use, you may lighten the vest by using a single large pack in each pocket. Ideal for office, home or recreational use, the packs are made with a proprietary high-tech, full barrier film that's hermetically sealed for easy cleaning, disinfecting or sterilization and is completely odorless. NOTE: These packs DO NOT fit the Flex Vest. If you need Flex Vest spare packs, search for "Glacier Tek Spare Flex Vest Adult Cooling Pack Set".
