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.
Nice product for the price. It’s a really nice helmet and can hear through headset perfectly. I like how helmet has an indented space for Thea speakers to mount internally. I also like the visor that can be flipped up.
Everything feels great. Helmet looks awesome. Fits really well. Surprisingly small headphone are really loud. I synced intercom to my Pan America HD and it works great! I also have Cardo on my other helmet and GDM is louder. I am hearing impaired and louder is better. I recommend! The price is great.
Buy it. It came in the mail in a few days, and the helmet is great quality. It weighs nothing and looks so cool. They package all the extra visors and the Bluetooth headset separately so you can truly make this helmet specific to what u want and need. The first day I rode w it I go thrown into a tree at 45 miles an hour and it saved my ass. 10/10 buy this helmet.
