I have a Zolowear ring sling that a friend passed on after her daughter was finished using it. It is great! My daughter is 9 months and, so far, I've mostly done the hip hold and chest to chest. I know there are a ton more holds I can do, but I need to watch the DVD again to figure out how to do them.
I love this sling since the fabric holds up quite well and the pattern is very pretty. It also has a large zippered pocked which can fit keys, a diaper, etc.
