This helmet overall is great. It's a modular helmet that has a vent on the top event in the back and the vent in the front. Keep the fog out. The Bluetooth speakers could be a little bit louder, but they sound great. The quality is great. The microphone is there and works perfectly. That's your calls with no problem. The music sounds great. Even going on the freeway at 80 mph. I do love the modular helmet. You can pull the face up. You can put the visor down. It does have a second visor. That's built in that. You can flip down as well and keep the main visor open to get air that came with a black and clear visor if and a pink visor that's actually full face module which that's the best one. I love that visor. Obviously I can talk about this helmet all day so check out their review the video and go get you one.

I was wearing this helmet, when a car turned in front of me, most definitely did its job. They replaced my helmet for making a comment on one of their sites on Facebook. That that tells me they care about the customer. only thing is I wish they would start sending the helmets in a box and not wrapped in the bubble. The replacement day scent Was damaged From shipping. So I am waiting for them to send me the part to replace on the helmet that got damaged during.
Shipping process, I love the headset. Easy to set up clear quality sound and hearing. Trust me , my 131 is pretty loud and I was able to hear the music clearly.
