What more do you want? I bought this for cycling, to make me harder for motorists to miss (or, more accurately, easier for motorists to miss, but harder for them not to notice me). It arrived 24 hours later, is a great price, and does what it says on the tin. It's not a colour you'd wear to work, it's very in your face, but on a bike, people will see you.
It's comfortable, thin and washes/dries very easily. Not sure what else to say. Job done
