Verified Customer Reviews for HJC F100 Carbon
Easy to wear and excellent to use
11 Oct 2025 by Paula
The flip over works really well - good weight distribution and easy mechanism.
The lightness of the helmet is great.
Looks and feels stylish.
Only criticism is that the internal sun visor does not come down enough - even with the minimal adjustment feature!

Really comfy.

Yrah as it says. Really comfy. The flip front works well and it's very quiet compared to my old helmet.
Glad i bought it. Also decent price as well.

Light weight and quiet

What a difference this has made. I previously used another flip style helmet which gave me nothing but issues. I found it very loud with wind noise and cheap. This however is completely different. Very quiet, so much so that when an earplug falls out (like the do), you can still complete the ride and not be deafened. It feels solid and well made. The sun visor covers your full field of vision unlike my last one. The weight difference is also very noticeable. My mate has now ordered one on my recommendation.

Description
The HJC F100 Carbon is a multi system helmet with an advanced fibreglass composite shell offering both lightweight durability and effective impact protection.
Combining the features of a full-face helmet and an open-face helmet, the chin bar can be flipped up to transform the helmet into a more open configuration. The rider can have the protection of a full-face helmet when the chin bar is down, and the convenience of an open-face style helmet when the chin bar is flipped up.
