Perfect for nature viewing! Our Vista 8x42 binoculars are designed for any observing situation - from birding and butterfly watching to lanscapes. They're full-size binoculars, yet compact, lightweight, and rugged as they come. Vista binoculars feature the finest BAK-4 glass porro prisms. Most importantly, every air-to-glass surface is vacuum-layered with multi-coatings, resulting in increased light transmission and contrast. Ample eye relief and roll-back rubber eyecups ensure comfortable viewing with or without eyeglasses. And their soft leatherette coverings provide a secure and comfortable grip. They come threaded for a tripod adapter and include a deluxe carrying case, wide woven neck strap, and lens caps. Twenty-year limited warranty.
