I like the feel and the looks of these caps......I have three of them. As far as cooling........I live near the Gulf in Texas and it is very humid here. The caps will absorb as well as any other caps but nothing can evaporate in this climate when the humidity and heat are high, which is most of the summer. Even a towel gets soaked and stays wet while out golfing. I am pretty sure the cooling effect would be better in a less humid climate. The caps, however, are comfortable and light and look good.
