An ideal companion for general-purpose glassing on the trail, at the stadium, or around town, theNikon 10×25 ProStaff ATB Binocularis equipped with space-saving BAK4 reverse-Porro prisms, a multi-coated optical path, and aspherical eyepiece lenses. These features work together to produce clear and crisp high-contrast views with accurate color rendition. Nikon’s proprietary Eco-Glass optics are made of environmentally friendly lenses and prisms that don’t contain lead or arsenic. Complementing the image quality, the optical tubes are nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging, and the housing is wrapped in a textured rubber armor that provides a slip-resistant gripespecially in cold or wet weather. Weighing less than 13 ounces and measuring a mere 4.5 inches long, the ProStaff ATB can easily fit in most packs, pockets, or purses without adding excessive bulk to slow you down.
