I love these hats. I've bought two. I have a taller head with 7-1/4 hat size and I can wear this very comfortably with all but two snaps of seven engaged on the snap-back. Best about this hat is it floats in the water! I've lost it on the river and recovered it everytime. The crown is not foam and the bill is a softer, flexible material that still holds structure well. A byproduct of this is that it is also extremely comfortable with no pressure points. By far the most comfortable cap I have ever worn! I've had them for 2 years and they have held up well. I recently lost one and will be absolutely getting another (it was floating but a serious injury on the water made recovery impossible for me).
