Yosemite BX-1 Binoculars from Leupold is a compact optic featuring a Porro prism design and a fully multicoated optical path. Leupold outfitted this binocular with BAK4 prism glass, and the Porro prism configuration displays more depth of field than roof prism binoculars. The resulting images transmitted by the Yosemite binocular have lifelike depth and are crisp across its wide 67° apparent angle of view.

A nitrogen-filled housing equips the Yosemite binocular for fogproof performance while its rubber armoring and textured ridges deliver a slip-resistant grip. Additionally, the binocular has a broad interpupillary adjustment range—its 50mm minimum interpupillary distance allows the Yosemite binocular to comfortably fit most children. Twist-up eyecups and a 15mm eye relief help to provide a comfortable viewing distance for children and adults alike. This item is covered by Leupold's lifetime warranty.
