Full-size binoculars can be too large for many people, especially younger users. Leupold BX-1 Yosemite binoculars not only fit smaller hands, but also adjust to fit the smaller interpupillary distance (the distance between the eyes) of smaller users…something most full-size optics can’t do. With both 6x and 8x models available, everyone from the youthful user to experienced adults can enjoy the optical performance that serious users demand. The Leupold BX-1 Yosemite binoculars offer the range of interpupillary adjustment needed for a universal fit without sacrificing optical quality. Protected by the Leupold Limited Lifetime Warranty.
