We build our optics to endure the toughest elements, no matter the class of binoculars. Knowing that outdoor adventures often bring you near water, we've designed the Neos series of weatherproof binoculars to withstand the unexpected. Built with a durable composite chassis, these binoculars are O-ring sealed and nitrogen purged for 100% waterproof and fog proof performance. Whether you face foul weather or take an accidental dip in a mountain stream, your Neos binoculars are ready-to perform. The rubber armor provides a secure grip in slippery conditions, while fully multi-coated optics and high-quality BaK-4 prism glass maximize light transmission and deliver crisp, clear images.
