UST Reusable Heat Pack

Hot and Ready

Whether you need to keep your hands warm out in the wilderness or just need to relieve a sore back after a long day, the UST Reusable Heat Pack has you covered. This chemically-powered heat pack contains a special sodium acetate and water solution that will heat up to 130°F (54°C) within 15 seconds of activating. The handy heater is activated by bending the enclosed metal disk until it clicks, which causes the solution to crystallize and provide up to 2 hours of heat. The heat pack is environmentally friendly, as it can be reused numerous times by placing it in boiling water (see instructions on package) to rejuvenate it.

My girls love these
May 13, 2019
Bought these for my girls. Priced low enough to give out as gifts. My oldest discovered that she could place them on her dash under the windshield and "recharge" them without boiling. They love them. Good size for the lower back when you get older.
