I was looking for a cover that was extremely durable. This cover did not disappoint. It's the best made cover I've purchased. I have many high end optics I need to protect not just in my safe, but out in the field. This cover has elastic to fit many scope sizes. It has a draw string to cinch down on the rifle. It also has cords to strap completely around the rifle to keep from falling off. I'd rate this 10 out of 10.
