QUESTIONS & ANSWERSAsk a Question
I have a large Arai Signet X helmet with a III 7mm liner. It is just a little bit too tight would you suggest trying the III 5 mm? and if it doesn't fit would I be able to send it back since 5mm is the lowest?
Hello, The Large Signet-X helmet does indeed have a III lining code. Yes, if you have a III-7mm and it's too snug the III-5mm should work for you. Keep in mind, that the liner relaxes the fit mostly around the top of the head. If you have a tight fit in the cheeks, it may not do too much. Also, a broken-in 7mm lining will fit very close to the 5mm. This is because the liner will lose some of its size during the break in period. You may not notice an immediate difference and it may only be noticed after the brake in period. Yes, the item is returnable for a refund. I hope this helps!
