Light, quiet and incredibly comfortable
27 Jun 2026 by Ben L
This helmet is very comfortable. I’m a large in Shoei and Klim and a large here. It’s a pretty neutral shape too.
The helmet is light and somehow quiet too. There is padding around the front of the ears to block out some noise. There is thoughtful channeling for comms wires and a generous space for speakers.
This is a premium helmet and the price is quite high but, unlike others, this comes with goggles, a photochromatic visor and clear visor and a few spare bits and bobs (as well as a nice storage bag). So, while it is expensive, it is the complete package.
I am over the moon with the purchase and sportsbikeshop had it shipped to me next day so no waiting around. If you want to try it on I believe you can order it to your nearest store too.

Super light

Swapped from my klim krios pro to this helmet, and got to say it surpasses the klim in comfort and ventilation. First run out was four days in the lake district and Dales, and can say I am over the moon with this helmet, faultless.

Feather weight and comfortable.

I am using Krios Pro needed 2nd helmet and considering X1 alpha. 9.5 beats Klim. The only small glitch is that at highway speeds that peak makes bit of rattling sound. But otherwise loved it. On a sunny day with photochromic wiser it has killer looks.

Great Helmet

It might be expensive but it's worth every penny. Really quite helmet. Sizing is spot on, I wear a size XL in Shoei GT Air 2 so ordered XL for this helmet and it fits perfect. Love the helmet bag that comes with it as well. Cardo Packtalk was a doddle to fit, speaker and mic recesses already in the helmet plus a groove for the cables to exit the helmet. Hardly know I'm wearing it it's so light.

This helmet is supplied with all you need to carry out your journey from road to offroad. It is supplied with photochromic lenses on both the visor and supplied goggles aswell as a clear visor supplied option.
The magnetic chin strap feature makes it quick to secure with gloves on too.
All in all a very comprehensive helmet, you get alot for your money.

This helmet is awesome it’s a bit noisy at motorway speeds but that’s to be expected from this kinda helmet. I love the photochromic lens it works really well and the you also get a spare and various other spares. The fit is perfect and very comfortable. Oh also it comes with some off road googles and a really nice carry bag. Well happy.
