The materials are great quality and I measured as specified for size and it’s a perfect fit! It came out of the package so soft and supple. I was a little bit concerned that there wasn’t an option for a cob size but the full/large size fit just fine, just as the measurements said it would. I purchased this in hope that it would help me as a disabled rider on a green horse, but even during the first ride I saw the positive effect it had on my horse by limiting my rein use and forcing me to use my legs and seat more instead. The handles are going to be a bit of a learning curve for me but I think once I get the hang of it, it will help me so much.
The only critique I have about the breast collar is that some of the buckles are a bit difficult to adjust due to the effort to eliminate leather “tails” at the end of the adjustable parts. It’s by no means impossible, just a little more difficult, especially for someone like myself who struggles with fine motor tasks at times.
