The leather TRUST bits, like teh Full Cheek Gag Bit, are particularly suitable for horses with a sensitive mouth.
The reason for this is the flexibility of the bit in combination with the taste of the leather.
The saliva production softens the leather bit and makes it more pleasant for the horse. The bits are provided with a core of reinforced nylon.
The leather is handstitched around the core and naturally tanned without any chemicals.
Highly sensitive mares accept this bit very well.
