Cara mengukur: Ukur lilitan kepala anda kira-kira 2 cm di atas kening, melalui bahagian betul-betul di atas telinga dan mengelilingi belakang kepala. Carta ini hanyalah panduan: sentiasa cuba helmet di rumah dan semak kesesuaiannya.
Bentuk kepala juga penting. Helmet dibentuk untuk kepala bulat, pertengahan (intermediate) atau bujur panjang, jadi helmet dalam saiz anda masih boleh menekan dahi atau terasa longgar di sisi jika bentuknya tidak sesuai.
Baca panduan kami untuk mengukur saiz dan bentuk kepala anda
Jika anda berada di antara dua saiz atau tidak pasti, hubungi kami sebelum membuat pesanan.

Quick shade from harsh light on everyday rides
If your daily ride moves between shaded streets and harsh midday sun, you can lower the HJC i31's integrated dark smoke sun shield when the glare builds, without carrying a tinted visor. The i31 is an ECE 22.06 approved open face helmet with a clear HJ-43 visor and an APC shell, which blends polycarbonate with ABS to balance strength with low weight.
The clear visor has an anti scratch coating, provides 99% UV protection and is compatible with a Pinlock 70 insert if you want to add an anti fog lens. A redesigned locking system holds the closed visor sealed against the helmet, and HJC has extended the sun shield by 5 mm to cover more of your view from the sun. Extended cheek pads help reduce wind noise and hold the helmet steady around your face.
HJC's ACS ventilation moves air from front to back through one intake and two exhausts, helping carry heat and humidity out of the helmet. The moisture wicking, quick drying crown and cheek pads come out for washing, glasses grooves make room for your eyewear and a micrometric buckle keeps fastening simple at frequent stops. As an open face helmet it has no chin bar, so it suits riders who prioritise an open view and easy stops over the extra facial coverage of a full face or modular helmet.

If you want a chin bar, the HJC C71 offers full face coverage with an integrated sun visor and a Pinlock 70 compatible visor.
Yes. An integrated dark smoke HJ-V12 sun shield lowers when the light is harsh, and HJC has extended it by 5 mm for more sun coverage. HJC advises using tinted shields in daylight only, so we recommend raising it at night and in poor visibility.
Can I fit a Pinlock anti fog insert?
Yes. The HJ-43 visor is compatible with a Pinlock 70 insert, which sits inside the visor to help stop it misting up in rain and humid conditions.
Is the i31 a full face helmet?
No. It is an ECE 22.06 approved open face helmet with a clear visor and an integrated sun shield, but no chin bar. A full face or modular helmet adds a chin bar for more facial coverage.
What does ECE 22.06 approval mean?
It means the i31 has passed the current UN helmet regulation used across Europe. Compared with the older 22.05 version, testing adds more impact points on the shell, an angled impact test for rotational forces and a visor test that fires a steel ball at the visor at 216 km/h.
Can I wear glasses with the i31?
Yes. Grooves in the interior make room for the arms of your glasses.
How do I wash the interior?
The crown and cheek pads come out. HJC recommends washing them by hand, or on a delicate machine cycle, then letting them air dry without a spin dryer.
