These things are great and worth the 10-15 bucks. If you are going to spend 300-700 dollars on an optic you should at least kick out 10-15 bucks for some sort of protection. Its a neoprene sleeve that adds a little padding to the optic and keeps the generic dirt and dust off the lenses. In a rainy enviroment water will soak through, thats how neoprene works but for sunny days at the range or trekin through the brush this little guy saves your finish and lens.
Pros: fits, prevents generic dirt/dust scratches
