Great helmet. Excellent build quality. Loads of features and fully customizable fit. Pricey, but you get what you pay for.

great helmet,

Best helmet I've ever owned, period

Exceptional. Fitment, weight, aero, noise and field of view are all best in class. I bought a black one, and liked it so much I bought the Escalate version. The reviewer that said it could be quieter is a nut. I have Arais, Schuberths, and others, and this one is about as quiet as you're going to find? which is surprising given all the ports for venting. Helmet looks great, and the performance on road is 10/10. Highly recommend!

Shoei

Fantastic helmet. Great quality. Shoei is a bit hard to get parts for right now if you need them so be aware of that going in.

Shoei X Fifteen

The X Fifteen is the best helmet I've ever owned. It wasn't cheap but the quality is amazing and the fit is superb. Field of view is unmatched. I own two other Shoei helmets, GT AIR and RF 1400. Both are great but neither comes close to the X Fifteen. If you can afford this helmet, BUY IT! You won't regret it.

Wish I didn't spend $1100 on a helmet that can potentially make me deaf

I have 3 street helmets: Shoei RF1400, Aria Corsair-X, and now a Shoei X-15. I've had it for 6 months and old used it 3 times, because it has the best ventilation of any full face helmet on the market. It is the only helmet I can wear when it is over 110 degrees outside. The fit and finish are first class, better than the Aria (especially the finish part). Now for the downside. This is the noisiest helmet I have ever worn. The wind noise is deafening. Even with ear plugs. I called Shoei, and the small a** that answered my call, said: "you bought a race helmet, what did you expect. It was not designed to be quiet". Now my Aria Corsair-X is perfectly acceptable, noise wise. I just got a basic finish that does not hold up to the elements like the Shoei's do. Aero on ... MoreI have 3 street helmets: Shoei RF1400, Aria Corsair-X, and now a Shoei X-15.

Now my Aria Corsair-X is perfectly acceptable, noise wise. I just got a basic finish that does not hold up to the elements like the Shoei's do. Aero on the Aria is slightly better (I have the accessory wing), but the padding is less comfortable and the visibility is slightly more restrictive, mostly due to the useless visor vents that Aria refuses to get rid of, that have never done anything for me before. How can the RF1400 be so quiet, although it is less aero at high speeds. If I had it to do all over again, I would buy 1 size smaller RF1400 and replace the internal pads with just a thinner option. I buy all my helmets from Cycle Gear. They are the best. Sometimes you make good choices, sometimes not.

X-Fifteen greatness

A very comfortable helmet with a sleek design for higher speeds on and off the track! Truly a great helmet!!!
