HJC I70 - Plain

The HJC I70 is an entry-level full-face featuring an advanced polycarbonate shell, ventilation system and new Vision Plush Wide shield.

As the follow-up to the HJC IS-17, the I70 brings all the design, protection and ventilation of HJC's premium range, at a highly competitive price. The low-profile, polycarbonate composite shell provides a superior fit and comfort using advanced CAD technology, with a high level of impact absorption and durability, and aerodynamic performance.

The I70 features an effective ventilation and exhaust system, comprising 5 top and lower vents for a high level of airflow from front to back to flush heat and humidity, with reduced wind noise. The new Vision Plus Wide Shield, dubbed the HJ-31m, gives you a wider field of vision and an additional 10mm at the top of the eye-port when compared to the IS-17. The internal sun shield has been repositioned to the bottom of the visor for reduced eye strain and improved UV protection.

The removable and washable interior is designed to keep your head fresh and moisture-free throughout your ride, with moisture-wicking and anti-bacterial properties. The I70 uses a simple and comfortable ratchet chin strap fastening system.

The average review for this product is 5.0 stars

Too many characters!

Fits well, if you size up.
Purchased a medium to begin with, however, that was a touch too small for me. I am 58cm but a large was perfect. Installed a Sena comms system inside with no issues or comfort problems, no hard spots in the lining either. Comes with a Pinlock max which is excellent. Expected quality from HJC. 4 star Sharp rated helmet, for the price, it can't be beaten. 1st time using Infinity Motorcycles, highly recommend. Customer support was excellent.
