Optics for everywhere, the 25mm Zero Tube monocular is the smallest, lightest, most durable, and highest quality way to seek the unseen. Made for the backcountry, these are at home on your biggest epics when line spotting, animal peeping, and going full send. Light enough to forget you have them, and durable enough to survive whatever you dish up.

The rugged no-slip grip keeps these protected and comfortable in-hand no matter what you (or Mother Nature) throw at them. Featuring ED glass and fully mulit-coated lenses, the Zero Tube provides the clearest images of the terrain ahead. Built to roam with confidence, the Zero Tube is waterproof with a IPX7 rating and fogproof with nitrogen-filled internal chambers, so you always know what lies ahead.

Fully Waterproof + Fogproof — IPX7 Waterproof and Nitrogen Sealed to Prevent Condensation. Whether you’re traveling in the backcountry in inclement weather or accidentally drop your Zero Tube in a puddle on a neighborhood stroll, this monocular is as rugged as they come. Submersible for 30 minutes in up to 3 feet of water, meeting IPX7 waterproof criteria, Nocs dare to go. With a medical grade O-ring assembly, and injected with inert nitrogen gas, this monocular will never fog up in the field, guaranteed.

Supreme Clarity — Fully multi coated ED glass with Swiss designed BaK4 prism. Each Nocs monoculars has 10 pieces of glass in both cylinders, each piece layered in anti-reflective coating with a low refractory index. Each surface is coated with multiple layers, for a crisp, bright image, and color clarity to the edge of the field of view.

Easy to Carry — Built to travel with a magnesium frame and integrated clip. Traveling with your optics has never been easier thanks to the Zero Tube’s integrated clip system that allows you to securely attach your optics to pretty much anything including your frameless UL backpack or your jeans pocket (you know, that weird small pocket originally designed for lighters).

Built to Roam — Built to travel with a rugged wave grip exterior. Weighing in at 205 g (7.2 oz), the Zero Tube is there when you need it and disappears when you don't. It's true, the ridges on the product look nice, fit well in small and large hands alike, and provide plenty of grip - and it also doubles to protect the optics from impact by dissipating impact force. Patented.
