    Impressed

    Highly impressed with the quality of the helmet. I have a large forehead so the XL is still snug at the forehead but it fits nicely. The Bluetooth/intercom system works great. I wish the speakers were a little bit better and the microphone be a little bit longer for closer access to the mouth, but it works. My wife and I both have a helmet and we honestly get close to a half mile coverage on it. Shipping was actually pretty quick considering. The music plays at a low volume but it is sufficient at 80mph to still hear and talk. All in all, an investment well worth the price.

    K4 modular helmet.

    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.
