This design can be used in 3 ways:

1.) Straight Sidepull
2.) Endurance Headstall - when used with bit hangers and bit.
3.) Bitless Bridle - by changing 2 pieces, the sidepull converts to a Bitless Bridle. The conversion is easily accomplished by just unbuckling the throatlatch. The 2 piece chinstrap makes the conversion an easy process plus makes it easy to adjust the chinstrap. See photos below.

This biothane Sidepull/Bitless Bridle Combo has a soft noseband made of a Beta, purple Biothane overlays on nose and browband.
