Size Chart for the HJC IS-Max BT Sprint Modular Helmet
Wrap a tape measure horizontally around your forehead. Select the helmet that is the closest fit to that size. A helmet should fit snug on your head. If it moves while wearing, it is too large. If it is painful to wear, it is too small.
Comment: So I purchased this helmet as a replacement to a Scorpion Exo 500 that fitted too thigh on me. First impression was that the helmet looks very good. The fit is great and comfortable even on 200+ mile rides. It is bluetooth ready in case you want to purchase a bluetooth system for it. I just installed some speakers on them and the fit very nicely into the speaker pockets so you wont even feel the speakers there. Overall im very happy with the purchase and would recommend to a friend. The modular is a plus if you wear glasses.. This is just a great helmet..
