This hat is made out of lightweight cotton sheeting it doesn't hold heat and dries pretty quickly. Unlike nylon caps, it keeps you cool when you sweat in it, and it doesn't develop a sour smell over time. Nicely contoured to fit your head and shield your face.
These hats are a great option if you plan to wear headphone style hearing protection, as there is no button on the crown, and is instead replaced with a tab of loop velcro. The hat is a Richardson 862 with a mesh crown and adjustable snap back.
