I bought the Swarovski Green protective case because I wanted some additional protection for My Swarovski spotting scope. It went on easily and does not allow the scope to slide around or move inside it. Both the eye piece cover and the objective lens cover slide out of the way for unimpeded viewing or can be unsnapped and removed all together. It is also very weatherproof. I have used it on numerous elk hunts in Colorado when it started pouring rain and then quickly turned to sleet and snow. The case was completely dry on the inside when I took it off to let it dry out. The case is also very durable. I once accidentally dropped my spotting scope out of a 25 foot tower blind and was ready to cry right then and there. When I picked up the scope, the case was a little muddy, THANK GOD IT WAS CLOSED!!!! There was not one bit of damage to the case or the scope other than some mud which easily washed right off. Just a small testament to the quality gear that Swarovski puts out.
