We build optics to withstand the elements, no matter what class of binos they are. We figure if you spend any time outdoors you will be near water, and your equipment will spend some time in it. The Neos series of binoculars are built tough, with a composite chassis that's O-ring sealed and nitrogen purged to be 100% waterproof/fog-proof, so if you simply run into foul weather along the way or should you take a spill in a mountain stream, or for that matter take a spill overboard, your Neos binos are ready for it. Rubber armoring gives you a grip in slippery situations. Fully-Multi-coated optics and premium-quality BaK-4 prism glass maximize light transmission and image clarity.
BaK4 prisms - Bak-4 glass prisms reflect more light to your eyes which will give you brighter and sharper image.
Multi Coated - Multicoated optics effectively reduces reflected light and increases the transmission of light giving you a brighter image than normal single coated lenses
Long Eye Relief - Long eye relief can be particularly important for eyeglass wearers because longer eye relief allows them to still see the entire field of view.
Close Focus - Close focus is important for those who are nature observers and especially important if you are going to watch butterflies or insects
Twist Up Eyecups - Twist up eyecups with intermediate stops allow you to set the eyecups to the ideal eye relief for you eyes
Waterproof - Waterproof to protect the binocular in the harshest weather conditions or if accidentally submerged underwater
