Arai RX-Q Comfort Liner 5 5 12 12
OEM replacement Nothing much to say about this comfort liner: it fits as it should, will break-in as it should, and is new so doesn't smell like my sweaty head. I've replaced the comfort liner, cheek pads, and neck roll to freshen-up the helmet; after four years of wear the helemt was a bit stinky. October 26, 2015
It was comfy and. My arai rx-q helmet was a little big once it broke in so I ordered the 12 mm liner and it worked great it was just what it needed to b nice and fitting so it wouldn't move when riding. I usuAly wear shoei helmets in a medium and I was happy w them but after I got the arai from revzilla I won't wear another helmet but the arai. November 2, 2014
Drop in replacement. One advantage of buying a Arai helmet is that you can buy different thicknesses of liners for the same shell. After a while my size large liner did not fit as snugly as I wanted. So I just bought the medium liner, dropped it in and now my helmet fits as it should. October 13, 2014
makes helmet fit , it's a liner went from the 7mm to 10mm. Makes helmet fit perfect. But like all Arai liners for RX-Q. If you do not have a full head of hair. The forehead pad stitching at "liner frame" can rub you at the forehead. I just dented the EPS to eliminate this. But Arai should rethink this liner design. Thus I gave the comfort... average w/o the EPS denting that is required. Thanks for sending it so fast. July 29, 2014
May be just what you need. It didn't sort out my problem of having a helmet that was just too large for me but it's a great product if you need to adjust the fit slightly. Arai makes great products and I'm loving my helmet. January 13, 2014
Fine tuning you're ARAI I bought this liner to fine tune my RX-Q. My head measured right around 57cm, using the charts, I purchased a Medium. It fit like a charm during the break in period, but started feeling a little loose (loose as in not race fit, I prefer race fit). Purchasing a 15mm liner and cheek pads gave that extra dialed in fit that made the RX-Q a lot more customized if you will. I highly recommend a thicker liner if you want a tighter fit. November 22, 2013
Just as described The RX-Q fit my head a little looser than the same sized Vector. This tightened it up perfectly. I went to the 12mm. Terribly easy to remove and install. Makes me love the helmet even more with this level of easy modification. October 15, 2012
Arai Liner I replaced this with my stock liner... what can zI say but comfortable and perfect fit!!!! September 3, 2012

RevZilla Store asked: Why did you choose this?
William J: Hot summer riding in South Florida means lots of sweat so having a replacement comfort liner is a nice plus. Jun 14, 2015
Angus S: Replacing worn lining and padding in my RX-Q. Refreshing the helmet with new parts. Already replaced the TDF3 ducts. Jan 20, 2015
Ryan I: I got a big fat head. Jul 8, 2014
J S: my III- 7mm liner RX-Q was slightly loose. 10mm next step up Jul 7, 2014
Janpatrick B: I just needed a new replacement for my liner. Mar 2, 2014
Stephen H: XL RX-Q had just a little wiggle but L was way too small. Hopefully this makes up the difference. We'll see. Aug 28, 2013
Stephany M: I bought my RX-Q helmet in 2010. After 3 years of commuting and weekend touring in the desert heat, the helmet's liner has compacted. The helmet is now looser than I'd like it to be. A replacement liner should help resolve this situation and make my helmet fit like it did right out of the box. Aug 21, 2013
Christopher O: I wanted to make my MD RX-Q a bit more snug. I called CS earlier this morning, forgot the Zilla's name whom I spoke with, but he was very informative about the product and clarified which liner would be better for me. TeamZilla FTW!!!! Aug 20, 2013
A shopper asked: i have the Medium sized RXQ with a (III) 15mm head liner in it already, and it just after about 5minutes of wearing it, it gives me a headache, (it feels as if just behind my temple is being squeezed too much) what size should i go down to? the 12mm, 10mm or 7mm?

Thanks for your help

Robk1300s: Depends on how much squeeze you're experiencing. I'm sure you know that a helmet should be snug, but not give you a headache or feel like your head is being pinched like a zit. But too big won't protect you like it should. I would first check to make sure the helmet is the correct shape for your head. Many riders chose a helmet based on the graphics. If you haven't done so already, go to a local shop(s) and try on various helmets to see which one fits best. I used to wear Shoei, but found them noisy and not a good fit for my head. I find The Arai RX-Q to be a good fit for my head. It's the most important piece of equipment you have, make sure it's going to do it's job. Nov 7, 2011

AliB: If that much pressure is on your temples, you should go down to the 10mm at least. It's difficult to make a recommendation without seeing you in the helmet or without measurements, but I think the 10mm is the best place to start. Oct 25, 2011
