Q1.How long do cooling vests stay cold?
The packs will stay cold for approximately 3 to 4 hours, depending on your situation. For extended cooling, we recommend purchasing an extra set of packs (which are a great value when purchased with a vest) to change out when the packs are no longer cold. Keep the extra set in a freezer (or cooler), ready to go!
