great saving
I was hesitant about purchasing but took the chance. I'm so glad I did. The helmet came as described and fast too. I used the savings for another visor (blue). Not only was shipping free, but I also saved on taxes.

Excellent boots
Love my new boots. I actually forgot I was wearing new boots when I rode with them the first time because they just felt good and familiar. I’ve always used Alpinestars, but this change is definitely worth it. Also $100 less than alpinstar 7’s. My only complaint would be these definitely need insoles to make the soles more plush. Kind of hard with factory insoles.

Great helmet and great experience.
I decided to try Moto Psycho Sport and picked up an open box Shoei RF 1400 helmet for quit a bit less than full retail. Couldn’t be happier with the helmet and the quick shipping. The helmet was perfect, no damage and all the original parts in the box. I won’t hesitate to buy from them again.
