No size marked, but it fits just like the Met helmet (now sold) which was marked "Unisize 54-61cm". It has an adjustable headband.
.
No surprises here but the met I would say is top end of medium so not huge or tiny but fits the average head. Mine is 57-58 and it's fine. Presumably giro much the same.
