Want some relief from the scorching temps that have invaded the planet? Hammacher Schlemmer has the answer with its Insulated Cooling Cap. Featuring a patented Hydroweave system that utilizes the sun and “draws heat away from your head,” simply immerse it in water and it is said to evaporate the liquid the way that your sweat glands operate. It’s available in navy or khaki for $25.00. The funny thing is, we think we already created this concept, but we call it a cool shower without a towel.
