So it seems I'm the only person who actually has these glasses. On the surface they seem a lot like Native's Dash line. The lenses are even swappable between the Dashes and the Factor Maxes. Only problem is they fog incredibly. I tried dremeling some slots above the lenses ala Natives, that only helped a little. When they sunk in a sailing mishap I have to say I wasn't all that sad.Bottom line: For this much money, get Native Dash XP's.
