HJC i31 Iona Jet Helmet

The i31 jet helmet combines advanced APC technology, which offers a lightweight yet impact-resistant shell made of polycarbonate and ABS. The ACS ventilation system ensures optimum air circulation with three air inlets and four outlets that dissipate heat and moisture. The Pinlock-prepared HJ-43 visor provides 99% protection against UV radiation and has an anti-scratch coating. A pre-installed, dark-tinted sun visor provides additional comfort. The interior is moisture-wicking and the pads are removable and washable. Cheek pads are interchangeable in all sizes and the ratchet fastener on the chin strap provides a secure fit. Special goggle channels also offer additional comfort for spectacle wearers.

How to measure your height:

1 Head circumference

Measure your head circumference by placing the tape measure horizontally around your head. Guide it about one centimetre above your eyebrows across your forehead and around the widest part at the back of your head. Make sure the tape stays at the same height all the way around and is neither slipping nor too tight so you get an accurate measurement.
