    Wanted level 2 with no straps. Came down to this one or the Spidi warrior piece. Price won out.

    Yes, I'd love to give a proper review but FedEx has sent my package from MI to OH to MD to Chicago, IL to Countryside, IL, to KS to NM to AZ and SoCal. Well, it's getting closer, I'm in NorCal.

    First of all let me start this by saying I have dropped a considerable amount of money into the two wheel sport this past year. I have shopped at moto mummy dot com / revzilla dot com / partzilla dot com and a few other major apparel and motorcycle retail vendors, and NONE can even come close to the level of service / customer care and just down right best place to buy from. Not sure if reviews get read but if you do read these as a potential customer, literally go no further. They have been nothing but amazing working with my wife and I. Can’t speak enough good things about them. They’re bad @$$ people to work with.
