Drawstring

A drawstring may be threaded through a hem or casing (a continuous tube of material) or laced through holes, which may be lined with eyelets.

In 1996 the United States Consumer Product Safety Commission (CPSC) issued guidelines for drawstrings on children's upper outerwear to help prevent children from strangling or getting entangled on the neck and waist drawstrings of upper outerwear garments, such as jackets and sweatshirts.

Drawstrings on children's clothing are a hidden hazard that can lead to deaths and injuries when they catch on such items as playground equipment, bus doors, or cribs.

From 1985 to 1999, the CPSC received reports of 22 deaths and 48 non-fatal incidents involving the entanglement of children's clothing drawstrings.
