Too loud
Nice fitting helmet, but way too loud. Have to use ear plugs, otherwise I have headache after 15 minutes of highway riding. It sounds like I ride with an empty bucket on my head instead of a helmet.

Great Helmet
This is the best fitting helmet I have ever worn . The moveable face shield is great because I don't have to struggle with my glasses. Then when the sun is really in your eyes pull the lever and you now have sun glasses. I think it's a great helmet and it looks good to and comes in different design.I might even try the chin guard that's available to make it a full face helmet to use in cooler weather !!

Too small!
I ordered a 3xl and it fits more like a large (doesn't fit my head. Had to give it to a friend with a smaller head).

Love the Coolmax feature
Nothing bad to say: Comfortable , fit snug ,well vented and I enjoy the sun visor. I drive a scooter and often stuck in heavy traffic in full sun : Appreciate the vent and the Coolmax.

Nice helmet.
Great fit. But a bit too noisy. Plus you couldn't hook up a wired Harley com system to it.
The fit a finish was great.

Solid Helmet
I bought this over the winter and have only had it out on a couple of short rides so far this spring.
I measured at the large end of a medium so bought the large and it fits perfectly, nice and snug with no pressure points that I’ve found. It’s very comfortable and seems to be well-made.
Two drawbacks of note… the tinted sunshade is all but useless as it doesn’t drop down far enough (the bottom edge crosses right through the middle of my line of sight so not only annoying but potentially dangerous) and just as a convenience it would be nice to have a quick connect on the chin strap.
Overall a pretty decent helmet, though.

Questions
Can this helmet accommodate speakers for a Bluetooth comms device like a Sena?
The helmet has a plastic lip around the bottom that makes it very difficult to attach an intercom. It is possible to mount something like the Sena 30K using the adhesive option. It also has room for speakers with a cloth pocket that you can slip the speakers into.

Bought medium and it fit at first but became looser. Replaced cheek pads w size small. Better, but still loose. Looking to replace liner to give a smaller fit. Liner comes in XS/Medium and S/L/XL. Current liner says Medium. What do i get for smaller fit?
The liner is the same size for the small and medium helmets. If you are looking for a tighter fit, it is not possible. The larger liner is thinner.

What's the head shape for this helmet?
Round oval

Optional anti-fog, maximum seal double lens face shield available (sold separately) How does this differ from the one in the pictures? GMax OF77 Also concerned the helmet may cut out too much noise (would rather a half helmet but want full face shield)
The double seal shield is basically a winterized model of the shield. The one that comes with the helmet is for summer rising, and is only one pane.

Existe-t-il un attache pression. Quick attach qu'on peut acheter pour remplacer l'attache du casque?
L'attache n'est malheureusement pas modifiable.
