Front Range® Flex Harness

Light, Flexible, Engineered Knit Harness

Our ultimate in fit, comfort, and mobility.

Color

Selected: Deep Teal

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.

    Good Option for Active Dogs

    My border/Aussie mix seems far more comfortable in this version of the harness than his front range. The lighter material and the way it moves have him moving more naturally than he did in other harnesses.

    Front line harness

    I am very pleased with this flex harness. Through the years I have purchased 5 front line harnesses. All are still in use. I like the different colors. I use some in the winter and others in the summer. They are perfect after washing. I hang them to dry. I highly recommend.
