Soft Structured Carriers have common factors which include a back panel, waistband, and shoulder straps. Many use webbing and buckles to attach the carrier to the body while some use rings and fabric. Some have shoulder straps that form an H shape while others form an X shape. There are usually 2 waistbands: waterfall style which can be bulkier but potentially more supportive than the apron style which is more minimalistic and that often fit petite and short torsoed wearers better.
