The Trust Inno Sense Swales | Port | Hard | 20mm offers the function of a double bridle but in a simpler form. It can be used with two reins: one attached to the main ring for a soft contact, and the other to the lower ring for added leverage, similar to the effect of a Weymouth. The Swales features separate rings for the cheekpieces, which ensures that rein pressure acts solely on the lower jaw. The baby version has shorter shanks, resulting in a milder action than the standard Swales.

The mouthpiece is made from Inno Sense Hard Port material, a slightly elastic synthetic that is firmer than the medium version. It offers minimal flexibility and includes a port to provide tongue relief by reducing pressure on the center of the tongue.

This combination makes the Swales bit suitable for experienced riders seeking clear communication with horses that need more control without using a full double bridle. The hard port design enhances stability while maintaining comfort.
