Built for the walk and 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, hardware rated from 1,500–2,200 lbs, adjustable fit, and MIL-W-17337 nylon webbing that holds its shape under sustained load. Built for dogs that lean, lunge, and pull with their full body weight.
In the car — hardware rated for the forces that matter
The buckles and load rings are rated 1,500–2,200 lbs of force. Clip into a standard seat-belt adapter at the back ring and the harness holds where a standard plastic buckle can crack. The Eclipse is not crash-tested to an automotive safety standard — it's rated hardware for secure vehicle restraint, not a certified crash-test device.
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."
