The result is a slim, streamlined shape in which the lenses and prisms are in a straight line.<p><b>Waterproof/Fogproof</b><br> Products are O-ring sealed and nitrogen purged for total waterproof and fogproof protection. These models can withstand complete immersion in water and stay dry inside. The interior optical surfaces won`t fog due to rapid temperature change or humidity.<p><b>Multi-Coated Optics</b><br> Multi-Coated optics provide superior light transmission and brightness.<p><b>Realtree AP&reg;</b><br> Realtree AP camo is neutral, open, contrasty, and realistic. Everything a hunting camo needs to be – versatile and effective. The pattern also stands up to the real-life effects of nature.<p>
