Features

  • 2-IN-1 MODULAR FLIP-UP DESIGN: This modular motorcycle helmet features a convertible flip-up design that allows riders to switch between full-face and open-face configurations. The full-face mode provides more coverage during riding, while the open-face mode offers improved ventilation and easier communication during daily commuting, touring, or short stops.
  • DOT CERTIFIED SAFETY: Built with a durable ABS shell and multi-density EPS liner, this motorcycle helmet meets DOT safety standards to help absorb impact forces during riding. The full-face structure provides coverage for street riding, touring, and outdoor riding conditions.
  • DUAL VISOR SYSTEM: Equipped with a clear outer shield and built-in tinted sun visor, this modular helmet helps riders adapt to different lighting conditions. The outer visor helps block wind, dust, and debris, while the sun visor helps reduce glare during bright daytime rides.
  • REMOVABLE COMFORT LINER: Designed with removable and washable inner liner and cheek pads, this flip up helmet makes cleaning easier after daily rides. The padded interior provides comfortable support during extended riding sessions, helping riders maintain a more comfortable fit over time.

  • Excellent value. Great functionality. Be prepared to replace if you fall
Size: XX-Large Color: Matte Black
Excellent helmet but keep in mind the first real spill you have You're going to need to get another one. Your head will be fine but something will be wrong with helmet. I've gone through three of these so far. Fell off my motorcycle in the rain My head hit the ground twice and was protected however the inner sunglass visor lever broke and it would no longer stay in the upright position. The second one I had fell off my bike while I was parked and loading my compartment and when it hit the ground some plastic piece let's say along the back of the neck broke off and would not snap back into place and stay there I had to try to glue it and it's still came back apart again. I'm not sure if this is normal for all motorcycle helmets but I have dropped each one of the three helmets at some point or another on the glass visor side and the glass visor stays permanently scratched. I usually ride around with the modular part up using it as a kind of half helmet and keeping the sunglasses visor attachment over my eyes. After only a few weeks of riding around the sunglass visor gets extremely scratched and scuffed from various tiny debris that would be hitting my face otherwise. At the price point of only approximately $70 when I compare this helmet to other helmets that cost upwards all the way up to approximately 1,000, as this is my first motorcycle helmet I have ever had I think this is a great product for its price point and I won't deduct any stars because you can only expect so much from a helmet that is essentially as cheap as you can get and doesn't leave you with a concussion if you crash. ... show more

  • A Top Quality Helmet
I ordered an XL, I have always worn an XL, but this helmet fit like a large at best. So I ordered an XXL and it fits great. The helmet is fantastic, I love the way it looks, light weight but very good quality. The flip up design is perfect for me. I wear glasses and helmets always made it hard to put on and take off my glasses. But not anymore, it's esay to put my glasses on and off. The flip up sun shade inside the helmet is a real nice feature. And the helmet is very comfortable to wear. I have not had any fog issues as of yet. I give it 5 Stars, for the money you can't go wrong ... show more

  • Excellent value.
Size: XX-Large Color: Matte Black
I have been riding motorcycles for over 30 years. I have never bought a helmet for such a low price that has such good quality. It's comfortable & solid . I highly recommend it. You are not gonna get a better helmet for the same price. I ordered 2XL.... I wish it was just a little bit bigger but I can deal with it. if you're looking for a value helmet, definitely by this one. ... show more

  • Nice and good construction helmet.
Well, this helmet is nice and good construction which should gives good protection. It is not heavy. I picked the XXL but it is a little tight for my head. Overall, it is a good value. I recommend this helmet.

  • Size XL (61–62) does not match the actual dimensions. I’m 59.5 the helmet is still extremely tight.
Size: X-Large Color: Matte Black
I attempted to wear the helmet, but it is too tight and my head is squished. My head measures 59.5 cm, and I ordered the next size up, XL (61–62), to ensure comfort. However, the helmet is too small. The image showing the red sticker size XL is merely a sticker and could be mistaken?. If this is not the case, the measurements and helmet sizes are incorrect. I am uncertain whether the XXL (63–64) will fit me. It looks good, articulation works. I hope customer service helps to find the right size. ... show more

  • good value for price, gets you legal to ride
Size: Medium Color: Matte Black
PROS: solid fit, quick release strap, does as expected CONS: instructions unclear on everything except sizing, Issues with my specific unit: it came missing a screw that holds in the back bottom piece of plastic. i luckily have spares of the right size and find out its stripped. being a part that isn't there for protection and mostly for aerodynamics and style, i fixed it with some hot glue. EDIT: After purchasing a second one a size up, i have realized that if you need to slam it shut, its too small. the plastic bit that covers the bottom that was broken on my first one stops the clips for Bluetooth headsets, so if you get one, be prepared to take that part off or to make a hole in it so you can fit the clip in, thankfully that part seems to do nothing more other than be a dust cover and tiny amounts of aerodynamics. ... show more
