Watch Julia and Kurtis explain and demonstrate a quick way to switch out your ThermApparel Cooling Packs without taking your shirt off. 


  1. Wear your vest inside out so the opening to the packs is facing away from your body. 
  2. Lift your shirt up and have someone else pull the depleted packs out and replace with fresh new packs.
  3. Keep doing what you were doing and enjoy!
