Free Motion BreastplateHelp your horse move and jump more freely! Our Free Motion Breastplate does just that! It attaches to the billets at an angle that frees the horse's shoulder and doesn't restrict movement. A soft but thick chest piece folds around the horse's chest and keeps the saddle in place. Without the leg strap that goes to the girth, the Free Motion Breastplate moves with the horse and without shoulder restriction.
