Same features but way better quality than my old built explorer helmet
I purchased this helmet as a replacement for my busted helmet. Same features but way better quality than my old built explorer helmet. Cheek pads and cushions are thick and comfy. doesn't move around when on stays exactly where it should. Haven't had it very long so we will see if it holds up over time. The tinted drop down visor is dark and functions very smoothly. Haven't ridden with it at highway speeds yet but so far up to 50 mph I have noticed very little head movement caused by wind. I love the removable chin wind guard, if that's what it is called, little if any wind makes it to my comms mic. For the price you can beat it. I ordered a medium because the large that usually fits my head loosens up over time. It is a little snug but I prefer a snug fit over a loose fit.

Nice lid
Had to return my first order (way to small) went up 2 sizes & still squishes my cheeks pretty good, hope it breaks in. (Not a flaw with the helmet, just my face shape) Everywhere else is really comfortable and really well made. Wish it had a click buckle though. Great value. Overall I would recommend to anyone. Also has replacement parts available. (Lining/pads/visor)

Buena calidad, buen precio, sin embargo al no tener pinlock le debo calificar menos.

awesome helmet, worth every penny.
it's a great helmet, only thing I would change is make it a pinlock visor, but other than that seems sturdy. not quite a shoei but definitely bang for the buck.

Really nice helmet
I’m super pleased with his helmet. It is really comfortable out of the box. Luckily my son has he same helmet so I knew what size I needed right from the start. The only little thing I could gripe about is I have big hands and the buckle side of the strap seems close to the helmet and is sometimes fiddley for met to get it unbuckled with bigger hands. Other than that I really like it. I have noticed a lot of guys on group rides wear the same helmet so that says something too.

Fit
I measured my head and it came to be a medium and it fit a little tight but I do like it , it will not move when I am riding or in deep mud, I would highly recommend.
