Pro's: Once you get the hang of using your ring sling, they're really quick and easy to use. Great for quick ups for newborns. Handy for toddlers that like to be up and down often. You can breastfeed/bottle feed in this sling. Can be left pre-tied and you only need tighten it each time you put your baby in. They come in a range of patterns and materials (like the woven wraps mentioned above). The standard 2m ring sling will suit a range of sizes but also come in shorter and longer lengths to suit all body types. It's the perfect sling for a fancy occasion as they can look dressy and elegant. With only one layer of material over your baby, they are light and airy. As they're worn sash style over your shoulder, they're a good option for warmer days. They can be very reasonably priced.
Con's: It can take a lot of practice to get this carrier just right (but once you find your sweet spot, you're flying it). As it's a one shoulder carrier, it may not suit everyone, especially those with shoulder injuries. It may not be the best choice of carrier for a heavy child on a long walk, as many prefer a 2 shoulder carrier for this. There are a few different shoulder types so you're best to try each type out before you buy. There are gathered shoulders, pleated shoulders and hybrid shoulders and variations of all. As with woven wraps, ring slings come in a variety of materials, some which might take a while to "break in" (see woven wraps above).
