Additionally the UP 8x21 series binoculars offer a 9.2' close focus to observe closer objects in detail while maintaining an impressive 326' field of view at 1000 yds. The UP 8x21 series also feature a synchronized interpupillary adjustment and sliding eyecups for comfortable viewing. Also included is a carrying case, neck strap and eyepiece covers.
