The Sightmark Solitude Binoculars produce crisp, clear images from dawn to dusk. Its Bak-4 roof prism system features a straight tube light system, achieving maximum light transmission and allowing for a more compact design. With a smaller objective lens, these lightweight binoculars are ideal for travel and quick, short-distance observation. Built to withstand the harsh conditions of the outdoors the binoculars yield a durable rubber-armored, nitrogen-filled and O-ring sealed body, making them waterproof, fog proof and dust proof. The twist-up, adjustable eye cups provide a comfortable custom fit, helping to correct eye relief at any viewing position. Includes nylon carrying case, neck strap, lens covers and shoulder harness.
