Does anyone make a girth like the Mattes Athletico... but in synthetic?

I am looking for an anatomic girth with the general profile of the Mattes Athletico, preferably in synthetic (think Professional’s Choice style,) but either way, no sheepskin. Is this a thing that exists or is the Mattes product really the only one of its kind?

(Horse has massive shoulder and forward set girth groove, everything slides back, including me when I ride him bareback.)

Is this one not curved enough? I have it and my horse loves it. It’s very thin and flexible.

ETA: whoops! I just realized the Athletico style has the curve reversed from this one - sorry!
