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.

    Great harness for the warmer months

    This is an excellent minimalist, lightweight harness that dries quickly and goes through the wash with coming apart. The new color is also a plus because it matched my dog perfectly. I have a 30lb Aussie mix with a slightly elongated body and average chest circumference and the small fits her well

    Excellent Lightweight Harness

    This is my fourth Ruffwear Harness. All are well made and recommendable products. This harness and leash are lightweight and easy to put on for multiple daily walks. Also, receive many compliments about green color with my golden fur.

    Beautiful Teal color and love how lightweight it is!

    I purchased the L/XL for my 80 lb Labrador puppy and it fits perfect. I have about 7 different Ruffwear harnesses (one that is 15+ years old and a few others that are 10+ years old, all still being used!), including one of the regular front range harness, and they all are GREAT and worked well for my Great Danes, Labradors and a few rescue mix pups over the years. My Labrador puppy runs hot so we LOVE this new lighter fabric for him and I can tell he is much more comfortable in it. I like the regular one for winter time and this one for the warmer weather. And since he is a white Labrador, the Teal looks AMAZING on him- he looks so handsome! So it is a win win for all of us! I can tell the quality is the usual Ruffwear sturdy and reliable quality too. Ruffwear are the only harnesses I buy and have for 15+ years now!

    Fits my Borzoi nicely

    Really nice quality. My Borzoi is notoriously a weird body shape for harnesses but the front range flex fits great. Really nice quality. And very easy to get on and off.
