Torsion girths are specifically designed for the Torsion treeless saddles. They are made with the horse in mind with strong elastics at both ends to allow the horse to breathe correctly and efficiently.
They come in English and Western styles, in leather, Airnet or Neoprene materials. All Torsion girths are contoured to allow better movement. The Moon Girth is especially designed for the rounder horses and have a moon shape so the girth doesn't slip forward or backward.
