I bought a few sets of the VSN's last year or year before when RMATV had them and bought a lot of replacement lens . I figured they were good for mud races and backups to my 100% Racecraft's that were 5 times the price. Well they quit selling them a while back , so now I see they have them again, but called VSN 2.0. I was excited so I bought like 10 replacement lens and guess what ? They arent the same size as the VSN's they sold last year. So I just ordered the VSN 2.0 goggle so I could use all they lens I just bought.
