When your buddy's roost you but you can still see so you roost them back ..priceless.
Easy to install they work flawlessly I've put them through quite the paces with no trouble and the mud and water wiper at the top makes a huge difference keeping the moisture from getting behind the roll-off film.
Ive used these at 2 races in the rain now with good results. When properly installed on goggle they work great at clearing the goggle of rain and mud. I raced a national Hare and Hound recently with allot of rain and mud and they worked great.... till about mile 60.Then the pulley mechanism jammed up with mud and would no longer work. I should of had a second pair and changed them out in the pits at mile 40. After getting home I washed them out and they work fine now. These also work great in the Dust. This is my second set of roll offs the first lased 2 years approx. 200 hours until the string broke.
