Sprenger's Duo snaffle was the first plastic bit to come onto the market.
It includes an inner steel cable and a 3 year guarantee against breakage.
The Duo mouthpiece is very soft and flexible.
An extremely mild bit that is very kind to the mouth but due to the inner steel cable, very strong and safe.
It is suitable for young horses with delicate mouths and/or and horse that is too sensitive to accept a metal mouthpiece.
Also useful for horses that tend to develop splits and cracks at the corners of their mouth.
Excellent as a temporary measure for hard-pullers who have made their mouth sore, for lunging and long-reining, work in-hand, showing youngsters in-hand, etc.
