I've been wearing this hat for the last couple of months and rate it for a few reasons: it's breathable, it's highly adjustable and the mechanism to do this is also simple, you can easily clip it on to things, it's flat peak means it doesn't bend out of shape when stored in your running bag, the colour stands out (so people can easily work out it's you!) and the logo is cool too. Finally knowing it is the 'predator performance' has motivated me to run faster when chasing other runners. The hat has to live up to its name after all!
