Sinister X6 Goggle

Awesome for people with glasses

I was a little bit nervous I've never purchased goggles before but these were specifically made for my 509 helmet and they were made to fit over glasses These goggles areVery nice looking And what a difference I used to dread riding around on my ATV in the Winter time because of the wind and my glasses If not anymore I will definitely get some more writing time

Excellent Fit, Amazingly Fog Free!

These fit my 509 helmet like they were made for it (because they are). They have Excellent optical clarity. These goggles stay AMAZINGLY fog-free! I am quite impressed! These stay much more fog free than my anti-fog treated prescription eyewear. I have tried many goggles and these are my favorites, by far.

Perfect Fit in a 509 Helmet

I have used other goggles in my 509 helmet and there were always little gaps in coverage that were problematic in really cold weather. These fit the opening in the helmet perfectly with no gaps. A must have when riding in temps below 0 degrees F. As a bonus lens swaps are super fast and easy as well.
