My standard configuration is half helmet with prescription safety glasses by Liberty Sport.
I paid for the transition lenses so they're perfect in bright sun or after dark.
They have magnetic wind seals that are perfect for me. They do fog if I wear them under my full faced.
I've switched to contacts when using my full faced (when riding my ninja) but still prefer the half helmet with liberty sport glasses on the B.
There just isn't enough air flow for a full faced on the B, at least not with my Arai.
