Glacier Tek Spare Cooling Pack Set - for use with vest styles: Sport, Banox, Classic, Hi-Vis, Concealable

Ideal for office, home or recreational use, Glacier Tek adult cooling packs are made with a proprietary high-tech, full-barrier film that’s hermetically sealed for easy cleaning, disinfecting or sterilization. For added comfort, the packs feature horizontal cells that conform to your torso as you bend and stretch. The set fits all Original, Classic, Concealable and Sports cooling vests, replacing the Protect and Comfort packs formerly included with those vests.  A set consists of four large packs (10.3 ounces each) and four small packs (7 ounces each). Use only as many packs as you need to stay cool. 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.
