Our slings have a custom fit, just like the rest of our carriers. The difference with the slings is that the fabric can stay tucked inside the rings so you just have to slip it on and slightly tug on the tail after the first fitting. Like our other carriers these slings are washable so they are easy to care for. They also have no padding so they fold up to be smaller than the rest of our carriers. (Keeping in mind all of out carriers will fold to fit in your diaper bag)
