I have 3 GMAX helmets, including the 55 model, and they are all very comfortable and priced reasonably. I can wear sunglasses under the shield of the 55 with no issues. As with any helmet, I would recommend you try it on first before buying.

 

We have 2 of these and 2 of their modular's and we like all of them, no problem at all with the visors either, and priced right too!!!
