Nice Helmet Fits is good, quality is good and it's comfortable. Wish it came in a few other color options but for the price no big deal. Shield change isn't super easy, getting it off is OK, getting the new one on is a bit difficult but I don't plan on changing them often. Overall great helmet for the money. October 8, 2014
Great helmet! This helmet was a great buy at a great price. Add in the free, fast shipping for a wonderful online shopping experience. I like the feel of the helmet as well as the weight. Riding for long periods can feel as though you don't have anything on your head. I looked at other helmets that were much more expensive that didn't offer much more than the gmax48s. The platinum series also comes with a tinted shield at no other cost... this was a major buying point for me. August 11, 2014
Good for the money Fits tight but comfortable. A little noisy thru the visor. Good buy for the price. January 20, 2014
Great helmet This is my third helmet and Ive got to say its the most comfortable I have owened. Ive been using it for four months now and it still feels great, and now that its starting to get cold its actually been keeping my face warm. Its a great helmet and I would recommend it to anyone!

this is a great product for a great price good prices good products and it came with an extra dark shield it saved me a few more dollars. April 11, 2011
Gmax48 Street Helmet I ware a large but this one I went to a medium. It is a bit tight taking on and off and you need to adjust the ear cups but after that it fits pretty good. Wind noise is not bad and the view is great! The tinted visor is a plus and looks good! I also have a KBC that fits a little better. Overall I like the Gmax line. March 31, 2009
