Waist Measurement:

If you bend to the side, you will crease in the middle of your body; this is your natural waist. That's where you want to take your waist measurement.

Womens Sizing Guide:

Please note sizing is dependent on waist size not bust size.

ThermApparel recommends ordering a size smaller than your usual T-shirt size.
(If you wear a large T-shirt, a medium UnderCool will fit best.)

Cooling Pack Care and Storage Recommendations:

  • When not in use always store Cooling Packs in the solid state, this means the fridge, freezer, or a room less than 70F/21C
  • Cooling packs left in their melted state for extended periods of time will result in rapid aging and reduce the lifespan of the cooling packs.
  • When handled properly packs should last 2-3 years, and our recycling program provides deeply discounted replacement packs.
  • To wash your cooling packs, use warm soapy water in the sink. Do not put them in the washer, dryer, or dishwasher.
