www.sunglasshut.com sells mine,
the REVO Extreme Wrap for $194.99 ( US Dollar )
Expensive? yes. The wrap shape cuts the light from the side so you
won't have the glare on the inside of your lens.
Again they're a little fast looking for the cockpit, (the " I'll be back " effect ),
but think function. You have to try it to believe it.
