Like the entire Nikon Monarch ATB series, the Monarch ATB 8x36s allow you adjust the fit of the binoculars with multi-setting click stop eyecups, a feature particularly useful to those who wear eyeglasses. This feature combined with the precision aligned optics, which make it so you do not have to strain your eyes, allow you to have comfortable extended viewings. Like the entire Monarch ATB line, the Nikon Monarch ATB 8x36 binoculars are made with Eco-Glass (and so lead and arsenic free), and come with a travel case, binocular strap and lens covers. It is pretty much only the size of the Monarch ATB 8x36s that makes them different from the rest of the Monarch ATB line.
