Fits like a glove
- Familiarity: I've used it several times
- Fit: True to size
- Size Bought: Medium
Had read this helmet runs on the small side but I haven’t experienced this,I have been wearing a medium in a giro and this helmet fits the same.Good ventilation pretty light weight and the boa retention system works great.My head measured 55.24cm and had originally ordered a large but changed it to a medium and glad i did it was a perfect fit.
