Yesterday I received my Davida classic and V3 helmets. I also purchased the Aviator and Halcyon goggles. For the Davida Classic I can wear either of the goggles. For the Davida V3 I can only wear the Halcyon. But Davida also recommends the Aviator T1, T2 or T3 goggles. I’m impressed with the quality of both helmets and goggles. Thanks to everyone here for recommending Davida. I like the light weight and looks of the classic, but it literally provides no safety. Those racers back in the day had balls of steel! I ended up purchasing everything through Moto-Amore. https://www.moto-amore.com/ John was awesome and very helpful.
