There are almost no faults to this cap, it's comfortable, stylish and comes in a variety of colours.
It's brilliantly easy to adjust according to the size of your head, probably one of the best I have seen, similar to a traditional metal clasp but improved upon. After a while of it being on your head you'll forget about it, of course it's blocking out the sun for better visibility but that will just feel natural.
If you're a fan of Mizuno, like me, then go for this cap!
