Vortex® Crossfire HD Binoculars feature a High Definition optical system and fully multi-coated lenses that that provide clear, bright views with precise detail. Crossfire HD binoculars are sealed with O-rings to prevent moisture, dust, and debris from getting inside, making them waterproof. Vortex reduces the risk of internal fogging when hunting in areas of high humidity or rapid temperature changes by purging the binoculars with nitrogen gas. A durable rubber-armored coating provides a solid grip and makes the binoculars quiet in the woods. Vortex Crossfire HD Binoculars offer top-end optical quality at a reasonable price.
