Step 6: How to use.
Tie around you neck (or your dog's neck) and enjoy the cool, evaporative effect. It should keep you cool for 3-5 hours depending on the temperature outside. To regenerate it's cooling effect, simply soak it in cool water for a few minutes (1-3 minutes should do) and replace around your neck.
Your cooler can also be a heating pad. Soak in water as for cooling, then pop it in the microwave for 30 seconds!
Care: When you want to store the cooler, just let it sit out on a counter to dry completely and it will return to it's flat state. Hand wash in mild soap.
And for safety's sake, always wear sunscreen and keep hydrate when you are in the sun!
