Did you know that 33% accidents happen from behind? This nifty design fits most horse?s tails, and is made from 100% quality neoprene. It does not slip off and is adjustable by touch and close fastenings. This is a great piece of equipment for summer or winter as it does not overheat the horse and is very comfortable for him to wear. The best thing about it are the four large flashing lights, that really catch the driver's attention, when it becomes darker. It has an on/off switch with small easily replaceable batteries which are easily sourced. Sometimes the tail guard may be a little tight for cob tails so we suggest you turn it upside down, for a better fit. One size fits most tails.
