One of my favorite things to do is to go hiking, and over the years, I l received a few tips to keep myself cool on the moderate daysâ€¦ For starters, it’s constantly fantastic to wear a quality hat that provides shade from the sunâ€¦ The next thing I started doing was hooking up a fan to my backpack that blew air on the back of my head, but i also hooked up a mini solar panel to my backpack so that the fan would be powered constantly while I was hiking. It was a marvelous makeshift cooling system. I actually wished that I could put a portable A/C unit on my backpack, however I figured that would be too bulky, but sporadically when it was actually hot, I would soak my hat plus with the fan blowing air on my soaked hat, I felt great! Eventually I l received that there were hats that were designed for cooling purposes when people go hiking like myself and others or do other strenuous activities. I eventually decided to buy one of these hats with the built in cooling. The cooling plan was basically just soaking the hat plus there was a clip for the fan to blow on you. I already had the solar panel hooked up to my backpack so I could run the fan as long as I had sunshine. I like the hat with the built in cooling plan because it remains soaked for hours before I have to get it wet again plus it reflects the heat of the sunlight away so it particularly remains cool. It’s absolutely the best hat that I have ever bought!
