Stubben 1" NT Mono Stirrup Leathers These wrapped mono-stirrup leathers create the closest contact between horse and rider. They are made of a soft yet durable leather with a very hard-wearing nylon core for safety. The normal two layers of stirrup leather have been reduced to only one piece of leather, reducing bulk under the thigh. The innovative buckle design lays flat against the stirrup bar that reduces bulk under the rider's legs.
