Not sure? Here’s more info for you: Great feel & nice weight for soft communication with your horse. Julie recommends 9-foot length 95% of the time, but suggests 10-foot length for large or long-necked horses. Trail riders find 10-foot reins useful for allowing the horse to eat or drink without pulling the reins out of their hands, having to stretch out over their horse’s neck. Color code for each horse to make it easier to find in the tack room or trailer. Washable—throw reins in the washer & hang dry! Customizable lengths for ropers, mounted shooters & barrel racers–for no additional fee! Most custom orders are delivered in 2 weeks. Most orders ship same day.  Handmade in the USA.
