The Front Range® Flex Harness is built for the ultimate in dog comfort. By utilizing an engineered knit material inspired by performance footwear, this everyday harness conforms to and moves with a dog’s body through every stride for an exceptional, seamless fit. This precision engineered knit construction delivers maximum comfort with minimal bulk and seams, creating a lightweight breathability that reduces rubbing and chafing and allows your dog to focus on the trail ahead. The engineered knit process itself reduces material waste compared to standard cut-and-sew harness construction.

The harness features four points of adjustment, buckles for easy on/off, and two leash attachment points: an aluminum V-ring on the dog's back and reinforced webbing at the dog's chest to redirect dogs that pull on leash. Reflective trim and an integrated light loop for The Beacon™ boost visibility in low-light conditions. The expanded size offerings and soft construction make this harness ideal for companions of all breeds and sizes. The Front Range® Flex Harness takes everything you love about our best-selling Front Range® Harness and delivers it in a lighter, more agile design for high-energy adventures.

Complete the kit for the even greater comfort with the matching Front Range™ Flex Collar and Front Range™ Flex Leash.
