This HJC C70N review considers the ECE 22.06 full-face model with a polycarbonate shell, internal sun visor and ACS ventilation. The N version is assessed separately from the earlier C70: ratings or specifications for that older model should not be assumed to apply here.

Protection and construction
The listed approval is ECE 22.06. Check the exact helmet label and specification for the version you are buying, particularly if you need it for a track event.
Fit and adjustment
The chin-strap fastening is Double-D. Make sure you are comfortable operating that fastening and adjusting it securely before choosing the helmet.
Comfort and everyday use
The interior is removable for cleaning. Follow the manufacturer’s care instructions and refit the pads in their original positions.
Fit and the exact version
Try the helmet on before committing to a size: check even contact around the head and secure retention with the strap fastened. Shell specifications do not establish whether its internal shape suits you. If you use glasses or an intercom, check their fit with this exact helmet and the relevant fitting instructions.
