I was testing Barcelona rubber reins Full, black. I have never ride with rubber reins before. I have always thought - they are too bulky, too thick and not looking good. When I saw the picture of PSoS Barcelona rubber reins - they look so different, that I decided to apply for the test. Thank You PSoS, for choosing me!Overall impression - looks good like any product of PSoS. Great quality leather details, smooth finish, reliable junction of rubber and leather.What I like 1) the reains are not bulky at all. They are quite thin and with good grip, 2) my horse is feeling “borders” of reins better than textile reins I am riding with, 3) PSoS “cradles” attached to the bit allows the horse to stay in contact easier, 4) these reins are allowed in dressage and show jumping.What I am corcerned about 1) what will happen with the reins in winter time (at -15-20C). Will test that and write another review. 2) I allowed my students to ride with these reins their horses (ladies form 16-45yrs old), youngsters told me that they felt wierd, like holding Haribo bears in hands not the reins (they used to ride with textile or leather reins, the same as I do), but may be they just need more time to ride with these reins. Adults were satisfied with the grip. 3) I do not know how the green horse could react to the weight of reins on the bits. These would not be my choise for the introduction the young horse to the bit&reins.Will I recomend these reins - definitely Yes. They are handy and reliable.
