Product Review for the Martingale Seoul: Looks: The martingale is very well designed with the PSOS logo on the leather tags and the front piece of the martingale, the quality is outstanding, the leather is so soft! Functionality: Between the clip for the girth piece and the clips on the rein rings, I have to say that this martingale is the best one I’ve ever seen and used, it’s incredibly easy to use and take on and off without having to take the reins apart of undoing the girth which saves you minutes of your time tacking up! You can adjust both the neck loop and the length between the center piece and the girth piece so you can customize it to fit perfectly to your horse! Bonus: you can detach the martingale piece (the pieces you clip to the reins) and use it as a simple neck rope! It looks high quality, feels high quality and is so easy to use, if you’re ever looking for a martingale, I 1000% recommend this one, you will not regret it!
