My harnesses came full equipped for team use. Later, I called Bowman Harness, where the original harnesses came from, and ordered another team harness, as well as all necessary parts needed for single conversion. The accessories included large shaft loops and the tugs. Which leaves me wondering about a free-floating ring that is attached to the belly band, on both sides--just slightly lower than where my shaft holders hang. At first, I assumed they were to run the belly band strap of the shaft loops through, but it doesn't sit quite right when I do that. Can someone please tell me what the rings are used for? I have circled the ring in red, and again, it's on both sides of all my team harness.
