Zero Tube 10x25 Waterproof Monocular

The Zero Tube is our most advanced monocular—engineered for backcountry missions, fast movement, and demanding conditions. Featuring ED glass, dielectric-coated BaK4 prisms, and fully multi-coated lenses, it delivers exceptional resolution, contrast, and color accuracy in a form factor that all but disappears in your kit. This is precision optics for people who move light and look far.

Waterproof, fogproof, and built with a rugged, no-slip housing, the Zero Tube thrives in the alpine, on the water, and deep in the field. A built-in carry clip keeps it within reach, while its ultra-compact design makes it easy to forget—until you need it. When clarity, durability, and packability matter most, the Zero Tube is the one you bring.
