I have the Shires ones for field wear, I like the way they are structured to hold the mesh off the face. Just a bit wary of riding in something not designed to be ridden in though so wondered if these work well?
I used to use the Equilibrium version of this for my old mare, she is a photic headshaker and this stopped her. it worked well, i used it for hacking and schooling, i believe you can compete in them now too.
