Available in Emerald Green and Vibrant Purple 25mm polypropylene webbing with black cushioned mesh padding with black hardware.
There are two D rings on that harness, one at the rear and one on the front to help with training for pulling. Some choose to use the front or rear clip but using a training lead also offers additional control of being able to use both clips at the same time.
