Our Techno Harness® is a choke-free center-of-gravity harness that prevents trachea, hip, spine and organ injury in dogs 8-175 lbs. The patented material we incorporate into the Techno Harness® is also utilized inside NASA astronauts' spacesuits. This anti-static material actually absorbs or disperses heat when your dog is hot or cold. More features include: an emergency handle for lift-on-demand, and fully curved buckles to prevent friction. The Techno Harness® can also buckle directly into any vehicle using our Universal Seat Belt®.
