The MB04 Low Port Comfort Snaffle Bridoon with loose ring is designed with a large 1½ inch port with no collapse. It has independent side movement to allow for the riders need to lift the shoulder through each side independently and it assists jaw line flexion through better relaxation due to the greater comfort.

• MB04 Low Port Comfort Snaffle a Myler level 2 bit in the Myler system, (Mylers no-pinch alternative to a French Link) but with a port for better tongue relief whereas the French link plate acts directly on the tongue acting not on the flat of the plate but on its edge and this can cause tongue bruising and pain, the myler relieves this situation from happening. 
• The bit acts on the tongue as the rein is taken up and corners of bars, gently wrapping the lips, but the port gives more tongue relief when the bit is not engaged by the rider.
• Myler Level Two uses,   A bit that is successful in young horses and more experienced ones.
