I just got three Scopecoats after losing and breaking a bunch of Butler Creeks. They seem handy enough and the 2mm neoprene should provide some impact protection. By the end of the summer I'll know how they actually hold up.
With the covers was a product info. sheet. Scopecoat has another model called an XP6 Flak Jacket. This has 6mm neoprene and is available in designs made for large turrets. The company will also make custom coats to your specs. Scopecoat.com.
I am in the same boat so we just got a couple of the XP6 Flak Jackets thrown in with a scope (x2) purchase from Sport Optics and they seem pretty robust. I don't have any experience with other brands, these are what they recommended when we purchased the scopes and asked about protective covering options.
