The notices just didn't line up with my glasses so it didn't work for me. However might work for others .
Fantastic hat, i usually get flex fit but they stretch out after a year or two, so figured i would get the adjustable. Only thing i find with adjustable is they aren’t as deep as flex fit so that takes some getting used to.
The product is awesome i just ordered the wrong size and it’s too big for me.
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.
