The Swarovski Optik 8x25 CL Pocket Binoculars are a lightweight optic with the quality construction and viewing precision that nature enthusiasts have come to expect from the brand. They feature a dual-hinge bridge that allows the optical barrels to fold tightly underneath for a compact footprint that can fit in a pocket, pack, or purse. The folding bridge design also yields a broad 51-74mm interpupillary distance, so the binoculars are comfortable for a wide range of adults and children. High-quality glass bearing Swarovski's SWAROBRIGHT, SWAROTOP, and SWARODUR lens coatings deliver a crisp image with accurate color rendition across the entire field of view.
