This hat is good quality for what it is. I didnt really know what twill is, and that is really the only issue i have with the hat.. If you like twill, you will mostly like this hat.
If you don't know, twill is a more smooth material than what most hats are made of. It's also lighter. It attracts dust and lint very easily.
The bill of the hat comes with a strong bend/curve.. I like a decent amount of bend, so i'm cool with it. Though it is slighlty bent more than i would bend a new hat.
If you like a flat bill, or only a very slight bend, this hat might not work for you unless you want to hend it back, or if you can request it not to be bent.
