    • Very nice lid for the money
Color: Orange Gray Size: Adult-M
Just got mine delivered, in orange and silver. Easily the cheapest helmet I’ve ever purchased, though all the others before it were for street use, and this one is the first for use on my quad. First off, right out of the box it’s great looking and feels solidly built. The fit is perfect per the provided sizing chart; normally I’m a large, but the chart says medium for my measurements, so I ordered a medium, and it’s just right. Very comfortable on my melon, and the quick-release strap works just as advertised. On my head, it feels very light, lighter than any of my full-face street helmets, which is always a good thing. So far, without having actually ridden with it yet, I’m impressed with the quality of this helmet, especially at this price point. Definitely worth a look whether or not you’re on a budget. ... show more

    • Good fit and comfortable
Color: Matte Black Size: Adult-M
Helmet is great. Very comfortable. Enables rider to see while still protecting his face and head. Sizing guidelines were perfect after measuring the helmet fit really well.

    • I use it for MTB riding. Has not failed me yet
Color: Matte Black Size: Adult-L
I began riding mountain bikes, and didn’t know if I’d like it enough to I spend lots of money. So I bought this helmet. I fall right at the border line size for a medium. But went with the large just to be safe. It fits well, a little tight on the cheeks, but over time the cushion shapes into your face. Then again, I have gained a little weight only my face lol. I weigh around 255 and decided to ride trails to help me lose weight but also have fun. But I have heavy breathing, so this helmet does restrict some air, but I removed the front piece for now. It’s not too heavy. It’s light enough. I tried using AirPods with the helmet on. It’s kinda hard to put the helmet on without the AirPods being knocked out of your ears. But honestly. It’s a good price, the helmet is worth it. I purchased the black color. Looks nice. ... show more

    • Super nice helmet!
Color: Matte Black Size: Adult-L
The helmet came in a very nice box with great packaging around to also hide it since it’s a gift! The actual helmet is durable and feels strong! The matte black looks so good and on top of that it’s MassDOT certified which makes it even better!

    • Great price, built nicely and does not obstruct vision
Color: BlueBlack Size: Adult-XXL
This is a very comfortable helmet, built well and is not overly light or heavy. Visibility is not obsctructed when wearing. The only thing I would like is more padding at the rear towards the neck...like a neck pillow. But that is just me. The price was great and it fit my large dome of a head perfectly. The quick release strap is a must and has been used extensively with no issues. Also, no issues with stiching of the straps or interior padding. ... show more
