The IDC Longwalk dog harness from JULIUS K-9 in size 2XL with a blue-gray color scheme is designed for extended walks with medium to large dogs. This harness fits dogs with chest circumferences of 80-96 cm and is suitable for animals weighing approximately 32-41 kg. The innovative DuoFlex system integrates three actively designed connection points, where flexibly attached rings dynamically respond to the movements of both the dog and the handler, minimizing restrictions during activity. When off-leash, the harness can comfortably remain on the dog thanks to these flexible, active elements, as they reduce the feeling of wearing it. The design includes interchangeable patches secured with Velcro, allowing for personalization from a wide selection of available patches. Built for durability and reliability, this harness focuses on practical functionality for everyday use and provides secure attachment points without compromising dog comfort. The size 2XL ensures a snug fit for larger breeds, while the blue-gray color combination offers a neutral, versatile appearance. As a successor model of the IDC Longwalk series, it maintains the brand's commitment to high-quality materials and thoughtful design for active dog owners seeking reliable walking gear.
