DUO Eclipse PRO
Adventure. Car. Bulletproof.
The Eclipse is not about a mechanism. It is about construction. Mil-grade stitching, mil-grade fabric, buckles rated at 500–1000lbs of force. Built for giant breeds that need a harness that functions as equipment — on the trail and in the car.

Built for the walk. Rated for the car.
Most harnesses do one or the other. The Eclipse was designed from the start to handle both — and to handle the specific forces a giant breed generates in each context.
Control without compromise
The Eclipse gives you full control on the walk — multiple attachment points, adjustable fit, mil-grade webbing that holds its shape under sustained load. Built for dogs that lean, lunge, and pull with their full body weight.
Crash-rated hardware. Real peace of mind.
The buckles are rated at 500–1000lbs of force. In a sudden stop or collision, that rating matters. A standard harness buckle can shear. The Eclipse buckles will not. Clip into your car anchor and drive with confidence.
What Eclipse is made of
Giant breeds that need equipment, not accessories.
Newfoundlands, Cane Corsos, Great Danes, Saint Bernards, Mastiffs — dogs whose size and strength demand hardware rated to match. Dogs that ride in the car and need a harness that actually holds in an emergency. Dogs that have destroyed everything else.
The DUO Guarantee
Lifetime guarantee on materials and workmanship. If the Eclipse fails for any reason — we repair or replace it. No time limit, no fine print.
"I adopted a street dog from India — reactive, fearful, slipped every harness I tried. I couldn't find anything that worked. So I engineered something that did. The Eclipse is what happens when you apply that same thinking to construction instead of mechanism."
