I bought this hat to run in and keep my hair from my face as it is too short to pull into a ponytail. It is a lightweight "silky" material, sits well above my ears and serves its purpose well. I like the gray underside of the brim because it helps with glare when in the sun. It's adjustable with a
velcro strap in the back, but (maybe my head is small) the tab is longer than the place it sticks when I get it fitting my head. No big deal, though, I just fold it a bit to make it fit and not "flap around" or get stuck where I don't want it.
