The lightweight and compact Kowa 10x25 BD25-10 Binocular is intended for hikers, birders, and outdoor enthusiasts, with performance-enhancing features that include phase-corrected prisms with highly-reflective C³ coatings and fully multi-coated optics to produce bright and crisp high-contrast views with accurate color fidelity. A short 6' close focus makes it ideal for enjoying detailed observations of small subjects like feeding hummingbirds, butterflies, or insects. The housing is nitrogen-filled to make the binocular fully waterproof and prevent fogging when moving through extreme temperature changes. The combination of compact form factor and lightweight design make the BD25 easy to carry in a pocket, pack, or bag without adding bulk or heft to your load so you can carry them with confidence that you'll never miss a glassing opportunity on the trail, in the field, or at the stadium.
