You really have to be careful and watch the d-rings you buy at Walmart and fabric stores. They are often "split" rings which means they are not a solid welded piece and can slip off of the fabric loop they are fastened to on the harness...just be really careful. The ones from
www.cdwplus.com are solid welded and are not gonna slip off. I buy my velcro from
www.buyhookandloop.com...very good price!!! It is a small fortune buying it from the fabric store around here.
