The ultralight (2.5 oz) Sonoran SunShade was born out of hunting Coues Whitetail in the Sonoran Desert of Southern Arizona and Northern Mexico. Hunting "The Grey Ghost" requires hours behind binoculars, and the best glassing is into the sun because these little deer stay in the shady side of brush and trees.
It is versatile so that you can place it in the optimal location over your binoculars so that it block the sun and improves your view. When looking at an angle to the sun, the Sonoran Shade can be slid to provide shade and eliminate the glare.
The Sonoran SunShade will fit on most any binocular, and has been tested on Swarovski, Leica, Zeiss, and Vortex binoculars. It will also fit on any spotting scope or rifle scope.
