I have a very hard time finding hats that fit. I have purchased so far, 3 hats and they all fit. The notch system fits my sun and prescription glasses perfectly. I shoot a lot of pool and the notch holds my glasses of my face and I am able to see down table and close shots without the lenses being in the way. I highly recommend the hats and make sure to measure your size and the hats will fit and not be ginormous on your head.
Fits great with my Spyder frames!
This is well made, I really like the back-strap design, exceptional heat dissipation from inside ventilation scheme using a breathable netting.
Great fit
Not too hot for the tropics
Notch really helps with minimizing interference with glasses
