I have used these goggles for 20+ yrs. I have ridden Harleys across the U.S. , through the Mojave Desert, on Old Rte 66, Sun and Rain. Even got some Iron Butt Awards while wearing Mk. 8’s. These goggles are the greatest. Work wonderfully with and without a half helmet. I prefer the Laminated Glass lenses. I keep two pairs, one tinted (laminated) for day, and clear (laminated) for night. So much better than sunglasses and prevent dry eyes and fatigue which can accompany long riding days. One of the best motorcycle accessory purchases I have ever made. ⭐️⭐️⭐️⭐️⭐️
