Wow, the perfect bucket hat. The brim is just the right size and stiffness and it stays flat, not rippled, when down. The brim folds up on both sides without need for the buttons at all, but in heavier winds, the buttons are a nice option. I have not found it to be hot in the summer sun unlike a lot of hats and although it isn't waterproof, it holds up in rain. It feels a bit snug and the next size up was loose, but it is comfortable and I never have to use the chinstrap. The chinstrap is not removable, but once you remove the adjustment grommet, the chinstrap just stows in the hat with no trouble.
