It looks all worn out and gnarly - something that usually takes years of wear and sun damage. We have no idea how they managed this but we take our hats off to them. Sorry, that was appalling. It fits much like an RF hat does, which everyone seems to be wearing. This one isn't endorsed by Federer and it's probably not Wimbledon friendly, but it is sick. Looks sturdy, with double stitching almost everywhere and a chunky buckle for size adjustments. Nice on Aliexpress.
