Great option for achieving right fit After trying the L and XL Arai XD4, one was too small and the other too large. Adding the thicker comfort liner to the XL did the trick and now I have a comfortable fit. August 16, 2016
freshen up and fits better One of the benefits of spending the money on an Arai. Can always get replacement parts and can customize the fit with different sized liners and cheeckpads. I bought a liner one size thicker than stock and it's made my helmet fit even that much better and more secure. April 19, 2016
Makes my XD4 Fit Perfect This product really saved me from having to buy a new helmet. I measured my head and bought the suggested helmet size. When I got the helmet, it was a little tight so I proceeded to remove the customizing padding. The helmet then felt fine until wearing it for 6 straight hours. I started to notice it was tight up front and in the back and gave me a headache. I was well past the point of being able to return it. I bought the 5mm comfort liner and my helmet now fits perfect without any further foam customizing. April 21, 2015
Custom fit my xd4 fit on the loose side, so I ordered this thicker liner and cheek pads to make the fit more secure. I ordered a size med helmet when I should've ordered a small. The pads and liner were all that was necessary for a correct fit. The sizing chart was helpful February 18, 2015
Replacement liner to tailor the fit of my new XD4 Original equipment Arai liner. I wasn't completely happy with the fit of my new XD4 so I ordered a replacement liner to tailor it to my preference. The Revzilla price was better than the Arai website, shipping was less and it arrived very quickly. I now order genuine Arai from Revzilla rather than direct from AraiAmerica. December 8, 2014
Good for customizing fit This thinner liner is great for fine tuning the fit of the XD4. After going from the stock 5mm liner to this thinner 3mm liner in my size Large helmet, my helmet is much more comfortable on long days. July 2, 2014
Nice to have spares! Multi day trips in hot climates are made better when you can swap out the liner and cheek pads at the end of the day! Just put in a fresh set, wash out the stinky set, air dry over night and you back in business. May 21, 2014
