http://www.snowbigdeal.com/509-sinister-x5-goggle-black-fire.html | The all new Sinister X5 was completely re-engineered from the ground up and is a significant improvement over our original Sinister in almost every way. The result is an X5 goggle with vastly improved visibility, anti-fog, and durability. There simply has never been a snowmobile goggle of this caliber on the market!
