Since I ride in traffic and at high speeds on my eBike, I never felt secure using a bicycle helmet, so I took a chance and purchased this GDM helmet. I love it!It fits snug, but not uncomfortably; I recommend you order one size larger than your regular hat size. It has several vents to help reduce fogging with the shield all the way down on cold mornings; when it fogs up to the point where I cannot see properly through it, I just crack open the shield about 1/4 inch. I love how it comes with both a clear and a tinted shield, as well as the inside tinted visor that you can flip up and down with a slider on the left side of the helmet. It has a removeable 1/4" screw cover on top to mount a GoPro or other camera. It delivers with a nice, long sun visor/splash shield, which you can easily remove if you want to. It is VERY light (about one pound) but it is made very well and sturdy; it comes with the DOT safety rating, which means this helmet will protect my head much better than a bicycle helmet.Cosmetically, this is such a cool-looking helmet - I get looks all the time. When I ride in traffic and at high speeds I have the confidence that my head is properly protected, something I never had with bicycle helmets.
