The Nikon ® 8x25 Trailblazer ATB Binoculars fuse top-end optical performance with ruggedness. These binoculars feature bright, multi-coated optics, a rubber-armored body for durability and turn-and-slide eyecups for clear and comfortable viewing. They are also nitrogen filled and o-ring sealed to make the binoculars waterproof and fogproof while under extreme conditions.
