With a magnification-objective lens configuration favored by outdoor enthusiasts and outfitted with an exceptional eye relief and wide exit pupil that maximize viewing comfort, the Kowa 8x42 SV II Binoculars provide reliable performance from dawn through dusk and in all weather conditions. To deliver their performance, Kowa employs anti-reflection fully multi-coated optics, phase-correction prism coatings, and oil-resistant exterior lens coatings that work together to keep the lenses clean and produce crisp, clear, and bright high-contrast images with accurate color representation. Complementing the optical performance are construction details that make these binoculars durable and comfortable to use. They has a lightweight polycarbonate chassis and is protected by rubberized armor that gives them a secure non-slip grip even in cold and wet conditions. The optical tubes are nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme temperature variations and environmental conditions. A one-piece ocular rainguard covers the eyecups as the binoculars hang around the neck and prevent rain and spraying water from filling them, and it attaches to the included neck strap to prevent them from being lost on the forest floor.
