Cooling hat

Keep a cool head. Oh it may look like an ordinary cap, but in reality it is a top secret, nuclear fusion warp transmogrifier with...(enough..Ed) OK, so it's a patented evaporative cooling hat that uses a Hydroweave system to suck the heat away from your brain, doctor. All you need to remember as you plunk down yer $24.95 is that it's a cool product. Literally. 'You charge the hat by running it under cool water; after its excess water is wrung out, the hat keeps your head up to 30º cooler than the outside air temperature while keeping you dry and comfortable...The end result is a hat that actually cools you more effectively the hotter the air temperature.'
