This is a clean, Used helmet but I could not find the "used" option from the drop down menu.

Size M/L 57-59cm

The wheel at the back means you can adjust for a snug , safe fit.

The visor screws into the helmet so gives options and aides cleaning.

I have photographed the straps and inside so that you can see how clean it is. There is no ingrained sweat or mud although there are traces of dirt if you look closely in the nooks and crannies.

I have also photographed minor wear marks to the transfer on the top which is from storing the helmet.
