Let customers speak for us
Great fit
It’s a great fit on my 110 lb Rottie. She wears it readily - knowing a car ride is in the works .,.

OG Defender Harness - Crash Rated Dog Harness
We bought this in the summer, but recently started using it exclusively both as a seatbelt and harness to walk. The quality is excellent and I feel like my puppy is much safer in the car when securely in place with this harness. We will definitely look to purchase again when we add to our pack.

Highest quality
Every now and then you buy something that impresses you. This system is so well thought out and is such good quality. The hardware is all very similar to what we used in the aviation industry .

Optimus Gear Dog Harness
We purchased a blue, medium harness with seatbelt attachments and we couldn’t be happier with our choice of this product. We attended a pet expo near our home and found this product being displayed. We had hoped such a product would be promoted at this event and we were delighted to find it there. Thank you Optimus Gear for making car trips safer for our dog and worry free for us.

This harness is worth every penny, it goes on so easily, my dog likes wearing it, it’s appears to be designed to be compatible with common styles for coats and hoodies and it’s really nice on walks.
Most importantly it makes taking my dog for rides in the car sooooo much safer. It’s the best harness I’ve ever seen.

Andrew was such a great teammate during my recent purchase! He took the time to carefully explain everything to me. The harness fits my dog perfectly and is super handy when bringing my pup along to basketball practices.

Great product
I love this harness and the owner are very helpful. It’s so easy to put the harness on my dog I love the buckle idea. It’s so well made nice and strong. This harness I was searching for the perfect fit for my dog.
They are very nice company, you can ask questions and they will answer you and if you’re not sure about something you can send pictures to them or ask for a video to show you so you can watch it. It is worth it to pay the price for the harness to keep my girl safe in the car
Thank you so much for everything Andrew for helping me out to show me with the measurements and taking time with me to make the right harness size for my girl

FAQs
This system uses an upper tether that connects to the seat belt and your dog's shoulder area. The lower tethers attach to the harness: for small and medium dogs, they clip into the seat belt, while for large and XL dogs, they connect to the child seat anchors (available in cars made after 2004).

We use our in-house buckle technology, designed to withstand the forces of a crash. All stitching is also done in-house, allowing us to control the quality of every harness and ensure it meets the highest safety standards.
It's important to note that the same guy who typed this can also make every aspect of our harness system. Not many people can say that.
Not happy with the fit? No worries! Send it back, and we’ll make the necessary adjustments. Since everything is made in-house, we can fit any dog, no matter the shape. If you paid for custom measurements, we’ll even cover the return shipping!
It’s as simple as sliding it over the head and buckling each side. Designed for running, walking, towing, and of course, car travel—every step of this harness is easy to use!
