Bridging a comfortable middle ground between compact and full-sized, the Leupold 10x30 BX-1 Yosemite Binocular, in black, is designed with smaller objectives and narrower interpupillary adjustment range so they can be comfortably used by children as well as most adults. To help offset the lower light-gathering ability of the smaller objectives, the Porro prisms are phase-corrected and the entire optical path is fully multi-coated; which improves light transmission, color rendition, clarity, and contrast across the wide field of view.
Built for the trail, the Yosemite's optical tubes are nitrogen-filled and O-ring sealed to be waterproof and prevent internal fogging when moving through extreme temperature changes. The entire chassis is wrapped in a black protective rubber armoring that provides a slip-resistant grip in cold or wet conditions. These binoculars are offered here with a case and shoulder strap.
