BaK-4 PRISMS FOR OPTIMAL VIEWING EXPERIENCE: The prisms inside Nature DX ED feature quality BaK-4 glass with phase coatings applied to maximize light transmission and enhance bright, highly detailed images – especially in low light conditions.

DURABLE, WEATHER-RESISTANT BODY: A rubber-armored, polycarbonate housing protects your binoculars from damage and stands up to even the toughest weather conditions! They're also fully waterproof & nitrogen purged to prevent internal fogging of the lenses.
