Loop reins with snaps for quick and easy attachment. The snaps are permanently spliced into the rope and cannot be replaced if they were to break (which many snaps unfortunately do sooner or later). I do however also make loop reins with removable snaps that can be replaced if you would rather like that, you can find those
here.
There are 2 rope dimensions to choose from, 10 and 14 mm (3/8" and 9/16"), depending on if you prefer somewhat thinner and lighter reins or thicker and heavier ones. The red reins in the pictures are made out of 10 mm rope and the black ones out of 14 mm rope.
This particular variant also has a ring knot that marks the middle of the reins so you can easily see if your reins are even when you are riding. Since reins made of double braided rope are heavier than leather reins they can give your horse wrong signals if they are uneven, but if you have a middle marker on your reins you can easily avoid that.
If you want completely solid-colored reins you can choose the same color for the middle marker as the reins or you can choose a different color for a nice contrast.
