How does it work?:

• These cooling packs freeze solid at a comfortable 58° Fahrenheit, so they can be frozen in a freezer, refrigerator, or even a bucket of ice water.
• Once activated, these reusable packs deliver comfortable cooling for up to 2-3 hours. (Please note: cooling times are estimates and will vary depending on climate, body metabolism and activity.)
• Packs are non-toxic and non-flammable.
• Packs do not require a freezer! Packs can simply be submerged in ice water or placed in a refrigerator or freezer to activate.
• The cooling performance is not impacted by humidity or outside temperature.
