Does anyone know where I might be able to buy one? Too old to don the lycra, but I had a lesson on the lunge with a vaulting roller (so that the horse was bareback) as part of a course of classical dressage lessons in Portugal and I would like to try it at home. Actually may not try it on my bouncy arab will need to borrow a horse with flatter paces.... The Portuguese horses were extremely level in trot (less so in canter)
