One of the lightest binoculars in its class. Fully multilayer-coated lenses ensure image brightness and a crisp, clear visual experience. All lenses and prisms are made with Nikon’s Eco Glass, which is free of lead and arsenic. The fiberglass-reinforced polycarbonate design is highly durable, waterproof and fogproof. Rubber armouring enhances shock resistance and supports the firm, comfortable grip. Turn-and-slide rubber eyecups with multi-click adjustments facilitate positioning the binoculars to the correct eye point. The long eye relief makes it easy to enjoy a clear and full field of view, even for users who wear eyeglasses.
