Q. Last summer at Cub Scout day camp, the temperature hit 106 degrees. I like to wear a wide brim hat on days like that, but sometimes they just get in the way and a ball cap works better, especially when I’m out doing a lot of active stuff like running around or jogging. I find that most ball caps make my head feel hot and just retain more heat. I try soaking them in water and letting evaporation cool my head down, which helps a little, but I was wondering if you’ve come across any good caps that might have some ventilation in them.
