Knotty Girlz mecate reins are manufactured with premium double braid yacht rope or treeline. Mecate reins vary in length from 22ft. to 24ft. With numerous end options, such as poppers, horsehair tassels with rawhide buttons, and rope tassels, you will find something to fit your needs! When purchasing mecates with poppers on both ends, the working end will have a longer popper and the end that ties under the gullet or cheek will have a shorter popper. Looking for a halter/hackamore set? We have those too!
