It is very easy to adjust thanks to the four holes. The Dual CF dog harness is made of nylon and features a simple and basic design. The double strap it is made from ensures special comfort and strength, while the chrome-plated metal buckle makes the closure secure, adding a touch of elegance at the same time. This harness is available in classic white as well as vibrant colors like purple, light orange, and fluorescent green, with all harnesses featuring a black inner strap that creates a delightful contrast with the other colors. The Dual CF harness is available in four sizes that vary in circumference (from 27 to 53 cm) and in strap width (15, 20, and 25 mm).
