The shadow shade is the ideal shade for field observation while keeping concealed for your Grizzly Box Blind window system. The Shadow Shade allows some light to penetrate the blind helping aid your concealment from the approaching deer but giving the hunter ability to observe the field without giving away your movement inside the blind. Each window shade is applied to the window directly with easy attach clips so when you open the window the shade never has to be removed. See clearly without being seen by the wild game with this essential to your blind system.
