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.

    Flexwear harness and collar

    My dog, Remi loves Ruffwear Harnesses and the Front Range Flex looked like a lighter and cooler harness for Remi to wear during warmer weather. I purchased the harness and collar and it has been a great addition! Great quality and color. Fits perfectly.

    Improved Front Range

    Light and soft, yet secure. No complaints from the pup on a sweltering east coast outing.

    Great Lightweight Harness

    I have been using Ruffwear Front Range harnesses for years, but decided to try the light weight one. It is really nice, works great, and my dog Maggie seems to appreciate it. Already recommended it to friends.
