I bought these shirts to see if they would help while I work as a courier in this summer heat and humidity.
Day two I noticed the difference because I also experienced hot flashes while working. Yes, I still sweat "buckets", but I did not feel like I was going to pass out. I wear these shirts under my work shirts. I moved the collar of the shirts like fanning myself and immediately felt cooler. The length of the shirt is perfect for tucking into my shorts, so I don't get heat rash on my waistline. Looking forward to purchasing more of these shirts.
