5/5 Mr Curly Head - 22/03/2018 Quality (5) Value for money (5) Size up! Brilliant quality hat, fantastically warm and snug, especially with the flaps down over your ears. When you flip to this position, and extra bit folds down at the back too, offering a little bit of extra wind protection. Flawless condition, no tears, rips or faults anywhere. (removed the slightly tatty badge with a stitch ripper) As per the comments of Mr Fat Head, the sizing is very snug - perhaps it was designed for people with buzz cuts and very small heads? I have a 23cm head, but very curly hair, and the XL is a nice snug fit. Any smaller, and I wouldn't be able to use it. Basically, if you have anything but a very small head and are bald, go for one of the bigger sizes. Then again, it is so cheap, you could buy two and give away the one that doesn't fit!
