Good quality, but they are a tight fit for a large helmet.

Love the helmet. Fits great and is an amazing deal for the price. Will be buying another just like it for my wife.
The media could not be loaded.
Fit is great and very comfortable. The Bluetooth connection is a nice addition. Not the loudest, however this is good. It allows you to still hear around you fairly well. The 3 visors allow for even more customization. The backpack carrying case is decent as well.
I had somebody turn in front of me at 50 miles an hour. I have 23 broken bones. The picture is showing the inner shell. The outer shell exploded.. the paramedics said if it wasn’t for the helmet I wouldn’t be here. I had helmet approximately 18 months. Money well spent .
Fast shipping perfect fit great helmet with the bluetooth head set included
It’s been ages since I’ve worn a full‑face helmet, so getting back into one felt a little weird at first but wow, this thing blew me away. The build quality, the style, the whole vibe… way better than I expected. And the visor setup is awesome you get a slick drop‑down tinted shield plus multiple extra face shields on top of the clear and tinted. Total bonus. Even my husband was impressed, and he never touches full‑face helmets. I grabbed a small, and yeah, it’s snug right now but that’s exactly how a new helmet should feel. It’ll break in and mold to my head after a few rides.
Absolutely loving the style of this helmet, and the bluetooth audio punches way above its price. The fit is nice and snug without feeling heavy on my head, and the color is spot‑on — exactly what I wanted. Total win.
Nice helmet good fit. Would recommend them to everyone.
Great
Excellent comfort. Loud speakers. Well made and good value for the money
I love my helmet but the Bluetooth speaker quit working all together fairly quickly.
Looks alright but assuming it’s for a sports bike don’t be cheap, go buy a $400 helmet that actually protects you and will last you for several years
Weight of helmet is good. Fits good. I would say there is a lot of wind coming into from padding from neck.Helmet is comfortable and it’s not too much money. But the visibility goes and comes due to breathing into the visor
Very good helmet. On the quiet side for music but I love the ventilation. Will buy again from GDM
bluetooth does not stay on the helmet . other then that I would have gave it a 5 star so thats why i'm giving it a 3 star . if you can give extra sticky stuff to keep the bluetooth to the side of the helmet that would be great.
Brought it for my son’s birthday. He loves it.
It's a good helmet just seems very bulky and makes it hard to back up a bike with it on. Be careful when you have it on Bluetooth it will call 911 if you don't have your phone setting correct. 🤣 The padding is a bit extra so it does make it hard to snap the chin strap in the helmet. Overall decent helmet.
Overall I am pleased with my purchase. The helmet is light weight, but seems to be well padded in all the right places. The blue tooth unit is a little bigger than I expected but I'm ok with it. The blue tooth system was fairly easy to install, connected to my phone very easily, and seems to have good volume and decent tone. The only reason I did not give 5 starts I because I have not gone for a ride yet and cannot comment on performance while riding, but so far so good.
if you’re a small and measured your head abs can’t decide between a small and extra small get the XS the small is not a snug as i thought it would be. cheek pads could be a little thicker but the bluetooth is amazing 5/5 easy to assemble
Helmet and bluetooth awesome. 100% worth your money. Broken bluetooth contacted seller they replaced it immediately. You do not get customer service like this anymore. You will not be disappointed. Husband called on bluetooth through helmet (we bought two helmets) you could not tell he was on his motorcycle.
ordered for son this is what he wanted, he said works just as he had wanted
Great Helmet for the price, looks great and built well. Interchangeable visors are nice, not too difficult to change. Bluetooth is clear and loud enough on both ends for calls and easy to setup and use.
It would be better if the chin strap is a quick release
It was a tight fit at first but after using for a bit it's actually pretty comfy and it came with a Bluetooth/com kit definitely bang for your buck
This helmet is the total package and the seller was quick to replace a faulty Bluetooth device speaker with an entirely new device at no cost to me. Absolutely love the visor options and the Bluetooth battery life. Couldn’t be happier!

light weight android finish
It exceeded my expectations, I really like to recommend 100%.
Love the helmet. Fits great and is an amazing deal for the price. Will be buying another just like it for my wife.
Fits nice comfortable to wear. Got three lenses with mine. Easy swap out. Fogs easy need to apply some good anti fog spray I used magic worked good. Bluetooth works better than expected honestly. I have road most the day on same charge with gps and music playing non stop. Phone calls work great.
I have only used motocross helmets and recently picked up a dual sport. I wanted a helmet that looked sharp for on and off the highway. I was going to get the bell Mx-9 that looks similar but I love the way this one looks better. It looks futuristic Halo type. Fits great, cancels out the wind way better than I'm used to, and it looks great. For the price, you can't beat it. 100% but it again.
Package arrived earlier than delivery date. Very Comfortable, good visibility and quieter than I expected. I have installed the dark shield that came with the package and plan to buy a mirrored one as well. For the price this was an awesome deal.
