17.5" Antares Contact AO1 3A L M10 Flaps are grain. Kneerolls and seat are upgraded with buffalo. Comes with Antares comfort girth (52"), Antares leathers (145 cm/58"), Sprenger stirrups, Antares elastic breastplate (OS), and puffy Antares cover.  Antares leathers are calfskin with a nylon web core so they don't stretch.  Breastplate picture in ad that is hanging was taken as a "pano" so proportions look a little weird. Here are the measurements: Across the top: end of snap (on fourth hole) to end of snap = 31" Part of that that's the leather piece that goes over the wither = 12" Blue and white straps that go from the ring on the wither to the ring at the center of the chest = 26" each Leather strap that goes from center of chest to clip onto the girth (unbuckled) = 36" Saddle was ordered new in 2013 to fit my wide-shouldered, medium-withered warmblood. It served me well.  My horse has been sold and now it's time to sell my tack.
