Protects lenses from rain, dust and snow that can fog even the best scopes. Features polarized lens caps that give the shooter a no-glare image, even in the brightest conditions. Color and intensity can be adjusted from yellow to gray by simply twisting the eyepiece. Please note: Each scope requires two Polar caps. To select the correct scope cover, simply measure the outside diameter of the two scope bells, then reference the cover measurement listings. Select the cover with the closest measurements within .01" under size and .025" over.
