This vest probably will work in a lower humidity area, but the high summer humidity in the Carolinas prevents effective evaporation. Instead of feeling cool, it becomes steamy feeling in a short time. I tried wetting it before leaving home and then chilling it in the air-conditioned car until I get to my outside projects. I wore a thin cotton t shirt under it, but a quick drying t shirt might be a better alternative that I did not try. With the cotton t shirt, it gets warm too quickly. I had hoped to also be able to wear it under my ventilated bee jacket, but it definitely would not work as a layer. It does provide good visibility as you work in a field (as I was doing).
