After buckling this cover over your scope, you inflate it with air to create a cushion for your optic that will protect it from falls and hard knocks. The air valve, which is accessed through one of the top pockets, can be used to inflate by mouth or with a small included pump. The cover has a handle on top of it, giving you an extra way to haul your rifle around. Its clever design allows you to flip up the ends of the bag so you can shoot with the cover in place. You can also remove it in a matter of seconds. And the cover can double as a shooting bag or a pad to sit on during long glassing sessions.
