Zero Tube 10x25 Waterproof Monocular

No-Matter-What Lifetime Warranty

No questions asked.

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.

  • Extra-low dispersion (ED) glass sharpens resolution, improves contrast, and delivers more accurate color—so fine details stay crisp when you’re glassing terrain, wildlife, or distant lines.
  • Premium BaK4 prisms with dielectric and phase coatings maximize light transmission and clarity, especially in low-light conditions when seeing clearly matters most.
  • Rugged, impact-absorbing housing feels solid and natural in hand, with added grip to protect your binoculars when they inevitably take a hit along the way.
  • Ultra-compact form factor at just 110 × 40 mm makes the Zero Tube the most packable high-performance monocular in its class—easy to carry, hard to leave behind.
  • Waterproof (IPX7) means they’re built to handle storms, splashes, and full submersion up to 1 meter for 30 minutes—because weather rarely asks permission.
  • Fogproof construction with nitrogen-filled chambers prevents internal fogging as temperatures and conditions change.
  • Twist-up eyecup adjust easily for a comfortable fit, whether you’re wearing glasses or not.
  • Integrated carry clip attaches securely to packs or belts for fast, one-handed access when the moment appears.
  • No-Matter-What™ Lifetime Warranty backs every pair, so you can roam farther, use them harder, and worry less about the rest.

Seek The Unseen

Nocs was born at the Citadel of Excitement, with a dream of juicing every last drop of our time outside. We kept wishing we had a set of nocs enough times where finally one day we bought some. And we used them every day. Checking the surf. Exploring backcountry lines. Watching our raccoon pals emerge at night. Seeing the world differently. On a closer level.
