A pair of rein covers is perfect when the reins have worn the fur on the neck, or preferably before.
The rein covers are long and so narrow that they remain where you put them on the reins. These rein covers are available in 2 different lengths, 31cm with velcro fastening and 43cm which are channel sewn, which means that you need to thread them over the reins.

This is a very popular product during the winter months when the horse's fur is at its worst.
