Treeless saddle 13.5. Tag info is as follows from Circle Ystyle 1331 -4(rust suede seat)35(13.5seat)4(Regular oil)-05(wide) which fits all 7of my horses easily because of being treeless absolutely no punching in withers!  Love these designs can ride all day long and not get saddle sore just obviously dont tie on to anything with it!  This treeless barrel saddle was designed in collaboration with Jackie Jatzlau for barrel racers who want freedom to move (stand up) in the saddle without feeling constrained by the security of a typical barrel saddle.The treeless design provides the close contact that riders are looking for today along with the freedom for your horse to move naturally bending with the horse around the barrels and freeing up the shoulders!  I am willing to meet up with it
