I must say they are incredible, I have stomped on mine more then 20 times in front of customers and they truly are remarkable on how you can pull them out of the bag and they are perfect every time. I also fished September and October with them. Very good quality lenses and if your a hunter the interchanging lenses to clear make them great for riding and shooting.
