The Consumer Product Safety Commission announced today a recall of more than half a million UA Defender Chin Straps made by Under Armour in Baltimore. The faulty chin straps for football helmets have sharp metal snaps that may cut players.

According to the CPSC, Under Armour has received six reports of injuries that required stitches.

The recall involves all UA Defender Chin Straps, which were available in four color schemes: white and black, red, midnight, navy and royal. All the affective straps have a hard nylon shell, a padded chin area and a plastic strap with “Under Armour” printed on it. They also feature metal clasps that tighten the straps and attach them to the helmet.

The faulty straps were sold at sporting goods stores and Under Armour outlet stores nationwide and at www.underarmour.com from January 2008 through September 2011 for about $20.

Consumers are warned to immediately stop using the recalled chin straps and contact Under Armour for a free replacement chin strap.

For additional information, consumers can call Under Armour toll-free (888-823-0343) or visit the firm’s website at www.underarmour.com.
