Always carry a spare! A spare set of phase-change inserts increases your ability to function when you need relief from the heat. Swap out your spare set of recharged inserts to double the length of cooling you can enjoy to six (6) hours. Spare packs can be kept in the fridge, freezer or cooler for a quick change. Like the phase change cooling packs that come with your vest, these packs can also be activated in ice water.
This set of packs delivers a constant temperature of 58 degrees Fahrenheit for three (3) hours and do not require a freezer. If you plan on being outside for an extended period of time, store the packs in a cooler for easy retrieval and indefinite cooling potential.
