American made, patented, no-pull no-slip harnesses for large and reactive dogs

DUO PRO is built in Southern California. Engineered to stop pulling and escaping — so you can handle the walk.

Who this is for

We are not for everyone, or every dog.

We are the company you find after your dog has broken, slipped or pulled through everything else. Usually three, four or even five different restraints. When they have all failed, you start doing real research and that is when you find DUO Gear.

DUO Gear harnesses are built around a patented mechanism that tightens when your dog pulls or tries to back out of it. It's unique function is described by one of our customers as:

Behind it: MILSPEC webbing, T70 bonded nylon thread, 1000D ballistic nylon, metal hardware rated to 2,000 lbs, and stitching we shock load test to failure ourselves. Made in the USA, built in Southern California. Backed for life.

We build for the large and the hard to handle. The dogs you love, and cannot afford to lose.

The patented mechanism

One patent. Three builds.

The patented cinch mechanism demonstrated across the line.

No-pull cinch mechanism
DUO DIRECT

No-pull cinch mechanism

As one useer put it "disk brakes for your dog." Our patented system cinches down on your dogs body under leash tension, while directing their pulling energy back towards you. The best thing? Our harness will not rotate around. It grabs their body and stays put. Giving you both better control and a pulling deterrent.

No-escape cinch mechanism
DUO ADAPT

No-escape cinch mechanism

Our patented system adapts to your dogs body's movements, tightening when they try to escape, and loosening then they run or shake.

Security harness
DUO ECLIPSE

Security harness

When you don't need our specialized cinch mechanism but want the security of buckles rated between 900-2000 pounds, welded steel attachment points, Mil-spec materials, T70 thread and bar tack reinforcement at every joint. Perfect for outdoor adventures and car security. Dual leash clips on the front and back.

Patented Technology

Why it works when nothing else has.

Most harnesses are passive — they slide around, twist and pull off your pups body. The DUO harness is different. It adapts and responds to your dog's behavior in real time to give you superior control.

Step 01
Fits like a standard harness
Fits like a standard harness
Comfortable, padded, fully adjustable. Goes on like any standard harness and dynamically adapts to their body.
Step 02
Cinches against escape and pulling
Cinches against escape and pulling
When your dog pulls hard or tries to back out, the harness cinches — tightening just enough to remove their leverage and close the escape route at the same time. Their own movement triggers the correction. You do nothing.
Step 03
Controls like a collar
Controls like a collar
The patented system gives you similar directional control to a collar without the stress on the delicate throat anatomy.
