The go-to carrier for many parents of newborns through toddlers, ring slings offer quick on and off and a cool carrier for warm weather. Ring slings are a shorter length of fabric (from 65-85 inches) with a pair of specially made and tested aluminum rings sewn into one end. The rings work like d-rings to tighten the fabric. Ring slings can be made from a variety of fabrics: linen, silk, and woven wrap material (called a "wrap conversion") are the most supportive and comfortable. Ring slings provide a wrap-like feel but have a much shorter learning curve. Ring slings can be worn on either shoulder for front and hip carries.
