perfect feel, specialy with the Bubble Shield. happy with the buy.
Bought this helmet on a friends recommendation. And another friend always yelling at me about not wearing a helmet. Typically not a helmet wearer, and when I do it’s the half or “mushroom cap” type. Customer service was great. Used the fitment chart on the website. Was on the upper end of the Medium so went with it. Got my new helmet a few days later. When I took it out of the box, looked small and thought I’d ordered the wrong size. NOPE! Tried it in and fit great! Was very light and comfortable for being a 3/4 helmet. Loved the look, old school and simple. Have worn it a few times and honestly, really don’t even know it’s there. The chin strap is padded so doesn’t cut in to your chin. May get a visor and possibly a full helmet for colder weather. Very happy with this purchase!!!
Super pleased with my new Bonanza! This is a quality helmet and the Biltwell sizing chart was on point. I’ll definitely add a Gringo to my collection after seeing the workmanship.
Love this thing. Not bluetooth ready but I made it work. And I understand its supposed to be vintage but I need my tunes whilst cruising. Sue me.
