Is She Cool!

Or does it tickle!

JoAnn tried on my "Personal Cooling System", wrapped around her neck.

Rocke got it for me to take on my backpack trip.

Our wearable invention houses a patented, miniature evaporative-cooling system. Just fill with a few ounces of water, place around your neck and switch it on: A quiet motor drives a tiny fan that creates evaporative cooling; and the flexible sides hold aluminum cooling plates against your neck — and your entire body enjoys up to four hours of relief. What's more, the fan inside adds even more cooling by directing a gentle breeze over the back of your neck.
