Enter the Olivon EZ Explorer series, your versatile choice for hunting, birding, hiking, fishing or any outdoor activity where the day can come with a bruise or two. Unlike similarly priced binos, the internals are O-ring sealed and nitrogen-purged for 100% waterproof / fogproof protection. The tough, rubber armor keeps them protected at the bottom of your pack or while rattling around in the glove box. With BaK-4 roof prisms and multi-coated amber optics, EZ Explorer binoculars are over-achievers when it comes to gathering enough light to deliver edge-to-edge crisp, bright images.
