Vortex Optics - Diamondback 8x28

Diamondback 8x28 Roof Prism Binocular

With the compact 8x28 Diamondback, small size doesn't mean small performance! Like its namesake, the Diamondback rattlesnake, this pocket roof prism binocular packs a lot of wallop into a slender package. Featuring fully multi-coated optics, phase correction coatings, argon gas purging, and a unique checkered rubber armoring, the compact Diamondback doesn't trade performance for small size.
