The Peregrine10x42 are shockproof, fogproof and (US) Military spec waterproof, maintaining its peak performance at any temperature and under any conditions. Its rugged, UV- resistant rubber armoring is impervious to dust, moisture and even rough handling. The Peregrine's dark-green, light-absorbing rubber body blends in with natural surroundings, providing an advantage when searching for easily spooked animals. And, with close-focus ranges as low as 5.5 feet, the Peregrine will help you detect colour variations even with unexpected nearby encounters with birds.

They also happen to have a very long (approx 22mm) eye relief, making them the most comfortable binoculars I've ever tried, using these binoculars are a pleasure. Almost every time I've shown these to a customer I get the same reaction..."WOW!"
