Stretchy wraps are generally made of knits such as jersey or interlock. It is easy to take babies in and out of a stretchy wrap. This can be easier for the wearer as the sling often remains tied on and the baby is lifted out and put back in as required. Several factors influence stretchiness: carriers with any spandex or lycra content will tend to be very stretchy, carriers which are 100% cotton or other natural fibers will tend to have less lengthwise stretch.

All different manufacturers of stretchy wrap have a different amount of stretch, thickness and length.
