Mirror-coated highly polished glass prisms
Every component of our XT Binoculars is engineered to bring you the best performance and value possible. Each lens is carefully inspected by a professional craftsman. The highly specialized roof-prism phase-coating process involves individual application of 58 coating layers over a period of 30 days to produce near-perfect reflectivity. Optics are housed in a sturdy, nitrogen-gas-purged body sealed with premium O-rings for absolute waterproof, fogproof performance. The rubber armor protects the binoculars from all the abuse you can dish out, yet remains slightly soft for a sure grip in temperatures ranging from -40°F to 160°F. These features and more assure you of excellent performance and outstanding value when you invest in a pair of our XT or XTll Binoculars.
