Freedom of Movement
One of the most common complaints about dog harnesses, is the chafing of sensitive skin during normal activity. The ComfortFlex sport harness is specifically designed to avoid the most sensitive areas of your dogs body allowing a full range of movement at all times.
Dynamic Handle
Our leash connection ring slides effortlessly along the quick grab handle giving you increased control over your dog while walking, running or biking.
High Visibility
The woven, highly reflective webbing and a selection of vivid colors, make these harnesses easy to see in low light or dark situations when visibility is most important for the safety of both you and your dog.
Made for Comfort
The ComfortFlex sport harness is fully padded, not just over the back and chest like most harnesses, but around the entire girth strap so that those sensitive areas are not irritated, regardless of the level of exercise.
The ComfortFlex sport harness is ideal for active dogs, whether just going for a walk, a run, or involved in Flyball, Agility, Bikejoring, Skijoring, Nosework or any other high energy activity you enjoy with your dog. Due to the dynamic position of the dual quick grab handle and leash connection, any pressure generated is always directed directly to the chest, never riding up on the dog’s throat.
