Sierra binoculars offer good performance for little money in an attractive design. They are 100% waterproof and fog-proof - ideal for all outdoor activities, from hiking and hunting to sporting events and outdoor concerts. The new Sierra binoculars use BK-7 prisms and lenses, which deliver bright, sharp images thanks to their multi-coating. The nitrogen filling ensures that they are waterproof and fog-free. The slim roof prism design makes them comfortable to hold, and the centre focus allows you to focus quickly and easily. The Sierra binoculars are rubber armoured, and the large model is easy to use for spectacle wearers thanks to the twist-out eyepiece cups.
