Use them any place it is hot and you need to cool down to be comfortable.
Keep yourself cool during hot summer days, workout sessions, outdoor adventures or when someone has a migraine.
Perfect for vacations to hot places or if you work outdoors in the heat and need a quick cool down, it absorbs heat or sweat pretty quickly and takes a fair amount of time to lose its cooling effect but just snap it in the air and it gets it all back.
It's just the right size to wrap around your neck or head.
