Riders fear losing the reins. If you lose reins, you lose control of the horse. BOOMA connects reins to the saddle, so they are always accessible. Without BOOMA the reins can fall or get dropped or yanked, potentially entangling the horse. No reins means no control. BOOMA attaches directly to an English or Western saddle with sewn-in-swivel clasp. Designed for equestrian riders and ropers Carabiner O-ring attaches to rein Made of flexible, waterproof and durable polypropylene
