A multi-purpose harness, the Ruffwear Flagline Harness was specially designed to stand up to rugged outdoor activities while providing extra assistance for difficult terrain or crossing rivers and streams. The comfortable harness is fashioned from 150 denier polyester ripstop and has 75 denier polyester lining that repels dirt and dog fur. The three adjustment points on each side let you customize the harness to perfectly fit your dog’s body shape. There are two molecular-weight polyethylene webbing loops, one at the chest and one at the back, or an anodized 6061-T6 aluminum V-ring for leash attachment.

The easy-grip, padded handle lets you assist your dog across rough terrain when a small boost is needed. The chest belly panel helps with load distribution and eases tension when lifting your canine. Reflective material along the front panel helps improve visibility. You can also attach Ruffwear’s lights the Beacon or the Audible Beacon to keep better track of your pooch in low light or heavy brush.

The Flagline Harness is available in a wide assortment of sizes and six distinct colours. Please see specifications for additional information. Explore Ruffwear's full line of collars, harnesses, and seasonal and outdoor gear for any dog-friendly adventure ahead here.
