The CL-XY 2 is HJC's dedicated youth off-road helmet — not a shrunken adult lid. Youth-specific shells and EPS across four sizes mean proper proportions and weight for smaller riders on dirt bikes and ATVs.
A large eyeport fits youth goggles cleanly, ACS venting keeps air moving, and the plush Nylex interior is removable and washable — which, with young riders, it will need to be.

- Large goggle-ready MX eyeport
- ACS (Advanced Channeling Ventilation System)
- Removable, washable Nylex interior

Specs
- Certification: DOT FMVSS 218
- Shell: Youth polycarbonate
- Use: Youth off-road / MX / ATV (goggles)

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).
