I think I have the martingale that matches that. Not positive it's the same model but it's definitely by Red Barn. I love it! Seems like nice quality and it's held up well so far.
Not sure about the bridles but the martingales run big. This was the only oversized martingale I found large enough for my giraffe necked warmblood.
I spent quite a bit of time in Smartpak holding out martingales to compare it was significantly longer than the others.
