We build optics to withstand the elements, no matter what class of binos they are in. 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 binoculars are built tough, with a composite chassis that’s O-ring sealed and nitrogen purged for 100% waterproof/fog-proof so if you simply run into foul weather along the way or should you take 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. You’ll can quickly see when enjoying nature outside that no matter how well your plan on our part you and your binos my get a little wet.
