Care and Storage Recommendations:
- When not in use always store Cooling Packs in a solid state, this means the fridge, freezer, or a room less than 70F/21C
- Cooling packs left in a 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.
Consult your doctor or health care professional prior to using this or any cooling products for a medical condition. ThermApparel LLC will not be liable for injuries or damages resulting from the misuse or misapplication of our products.
