Introducing the all new Sinister XL5 goggle. The XL5 features our standard X5 frame with XL face foam. We increased the face foam coverage by 20% to fill any gaps between the goggle and helmet. This XL5 goggle was specifically designed for snowmobilers who wear 2XL-4XL helmets. If you've traditionally had small areas of exposed skin between the helmet and goggle, the all new XL5 is the ticket.
