The U.S. women’s national team’s dynamic right back has returned to action this week after suffering a brain-rattling concussion three weeks ago in the Washington Spirit’s National Women’s Soccer League (NWSL) season opener, but she comes equipped. For the World Cup tune-up game this Sunday against the Republic of Ireland, Krieger, 30, is going to be wearing a headband from Unequal, a company that makes protective sports gear.
