The sweaters have a drawstring around the neck area which poses a strangulation hazard to children.
Drawstrings can become entangled or caught on playground slides, hand rails, school bus doors or other moving objects, posing a significant strangulation or an entanglement hazard to children.
In February 1996, CPSC issued guidelines about drawstrings in children's upper outerwear.
In 1997, those guidelines were incorporated into a voluntary standard.
Then, in July 2011, based on the guidelines and voluntary standard, CPSC issued a federal regulation.
