I live in Texas where weather is very unpredictable. One thing I know for sure is Texas heat in summer can really knock you out. The $24.95 Insulated Evaporative Cooling Cap is a must gear if you are planning to visit somewhere hot.

By putting the hat under a running tap it will takes in some water that will be use to cool down your head and slowly evaporate. How much water will it store? Wouldn’t the water drips? The product descriptions have an answer for those questions:

The Hydroweave system combines hydrophilic (water-attracting) and hydrophobic (water-rejecting) fibers in a three-layer fabric that conducts body heat upwards, while retaining the cool water and releasing it slowly through evaporation; even while the middle layer holds onto water, your head remains cool and dry thanks to an inner lining that water cant permeate. The end resu lt is a hat that actually cools you more effectively the hotter the air temperature.
