Durable, Weatherproof Construction

The Sierra 10×50 is built for real-world use in all conditions. It is fully waterproof up to 1.5 metres and nitrogen-filled to prevent internal fogging. The robust polycarbonate body is rubber-armoured for added shock resistance and secure grip, even in wet conditions.
