The RPHA 72 is HJC's premium sport-touring full-face: a second-generation PIM prepreg composite shell — carbon on the Carbon colorways — built for long days at speed rather than short sprints.
A DMS drop-down sun shield steps through the light without a shield swap, and the HJ-48 shield seals harder than the outgoing design and ships with a Pinlock lens. An extra semi-neckroll in the anti-bacterial liner takes the edge off wind noise, and SMART HJC comms drop into the moulded pockets.

How to measure
Wrap a cloth tape measure horizontally around the fullest part of your head, about 1 inch (2.5 cm) above the eyebrows. Repeat a few times and use the largest measurement. The chart is a starting point — always try the helmet on for final fit.

One official HJC chart covers all models (full-face, modular, open-face, half); size availability varies per model. cm values are canonical (verified on both official US and EU HJC sites); inch values follow the mathematically consistent EU print where the US page conflicts with its own cm column (M and L rows). Note: many retailers still publish HJC's LEGACY chart (XS 53-54 … 3XL 65-66), which disagrees with the current official chart — do not mix them. Youth chart is the official Y10 chart (EU site).
