Spare Cooling Pack set for Cool Vests, 8 Cool Packs, 59 Degree, Recharges in 30 minutes;

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
