I have a couple different ones now , & have had a few different types of those side quivers just like yours Gary. We might have bought from the same vender in Washington. Very nice for 3D shoots.
I bought a very nice back quiver that i ended up giving to my son in law. I didn't like having the arrows spilling out every time i bent over to pull arrows, and catching the arrows on branches. I never did like reaching over my shoulder for an arrow.... never felt comfortable to me.
My favorite 3D quiver is a hip style. But i like a strap on bow quiver for hunting. Kirk
