  • Description

    With the Barska 25x100 Cosmos Binoculars, you'll enjoy sights that are out of this world.  Huge—and we mean huge!—100mm lenses are built to pull in the light from galaxies that are millions of light years away.  Just think what they can do on our own planet, or in our own solar system.  

    The Barska 25x100 Cosmos WP Binoculars are completely waterproof.  Don't worry about a sudden turn in the weather, or dew that might collect on your huge—did we say huge?—4 inch optics. All you need do is dry the binoculars off before storing them in the included hard case.  Fogging will also not be a problem, since the waterproofing method forces air out and then seals the body against moisture.  

    The Cosmos body is built of lightweight yet durable and strong aluminum, and is braced with a metal tripod mounting post.  This mounting post not only stabilizes the Cosmos binoculars, it provides a fast and easy way to mount them to a heavy-duty tripod.  Once mounted, the weight of the binoculars can be evenly distributed.
