Hot head? The Evaporative Cooling Cap will keep your noggin 20 degrees cooler than the surrounding air. How does it do that? The cap’s liner and brim are made of a special material that allows moisture to evaporate for hours after just a two minute “charging” in cold water. This cap looks like the perfect thing for golfers, gardeners or anyone else who spends time in the glaring sun and soaring temps this summer. The Evaporative Cooling Cap is available from Hammacher Schlemmer for $29.95.
