Giro Helmet Size Guide
How to measure your head size
To find the circumference of your head, place a tape measure in the centre of your forehead, wrap it around above your ears and around the back of your head. If there's a slight difference between two different sizes, always go for the tighter size.
Giro cycling helmets are adjustable so will fit a range of head sizes. Once you know the circumference of your head, select an appropriate helmet size. For example, if your measurement is 57cm then a size M (55-59cm) or a One Size (54-61cm) will fit you.
