I am 7 3/4 ish and Lrg sizing is perfect. It has a fire fighter helmet brim shape that I originally thought was odd until I made sure it was sitting properly on my head. After adjusting the cord and forming the brim I think it covers well and looks cool too. The "cooling fabric technology" is not just a marketing pitch. It really does work...at least for me. I've used for all day activities in hot conditions and never really thought about how hot it was. That says something I think. Fit and function make this a winner for me.
