Arai Quantum ST Medium £280

Anyone need a new Arai helmet? Perfect condition, frost black and comes with clear pinlock insert and box.
Bought last week and doesn’t quite fit and gives me a headache after a while.
My commute is 10 minutes so hasn’t been worn much.
Pick up from Borough Market.

Hi Blu - have a size large Arai Tour X4 - with clear and dark visors, visor bag and spare peak. It’s too big, hardly used. Would you be interested in a swap?

Hey, I usually fit in a medium but this is the wrong head shape for me. A large would be too big.
If you’re still interested or want to try out the Quantum, let me know; I work near London Bridge.
Also, I have a dark smoke insert I’ll throw in as well.

This still here. Call me maybe?

Still have this helmet if anyone is interested before it goes on ebay. Offers welcome.
