I have had these goggles for four and a half years and I use them at least 25 times a season. These are by far the mst durable goggles I have EVER had. even though they have the plastic frame, they hold up remarkably well and refuses to scratch. The lenses are also extremely scratch resistant, I have face-planted quite a few times and there very minimal scratches on them. The strap is great, especially the sticky grip that keeps them on your helmet. only problem with the strap is that it gets stretched after a while. Overall an incredible goggle, have NEVER fogged up on me, defintely worth the price.
