Which Bino Harness is Right for You?
At KUIU we know not all hunts call for the same game plan. We also get that hunters have their preferences. That is why we offer two solutions for stowing your binoculars and gear on your chest, the modular PRO G3 Bino Harness and the all-in-one PRO Chest Pack. This overview highlights the features, similarities, and core differences between the two.
If you’re a hunter, guide, or outfitter that does it all, everything from the minimalist approach to gear intensive expedition hunts, you likely need both.
PRO G3 Bino Harness

If you want modular customization, PRO G3 is the one to get. Built with similar functionality and appearance as our previous designs, this third-generation bino harness is fully stacked with upgrades. The most notable are the patent-pending Rail-Lock connection system, softer and quieter waterproof fleece-lined material, and an overall refinement of pocketing and layout.
With multiple purpose-built add-ons, there are hundreds of unique configurations to meet the demands of any discipline. We build Rail-Lock compatible holders for ammo, rangefinder, phone, hydration, bear spray, turkey calls, and accessories. It’s perfect for configuring your harness for different applications like scouting, archery, muzzleloader, and rifle hunting.

It has a larger overall size and more storage than the PRO G3, making it ideal if you’re packing items like electronics, emergency gear, muzzleloader quick loads, and larger optics.
