Lightweight nylon and mesh, no heat retention. This hat is basically a pair of sunglasses with how it gives you the opportunity to keep the sun out of your eyes and doesn't make your head any warmer while doing so. The advantage it holds over sunnygs is your ears don't get tired from doing all the heavy lifting.
Great hat for most heads with a soft strapback closure. An added bonus of this one is the soft brim. Toss it wherever and dont worry about it keeping shape.
