After suffering a concussion during a game in April, U.S. women’s soccer player Ali Kreiger is using a protective headband as her team competes in this month’s Women’s World Cup. Kreiger is donning the Halo headband made by Unequal Technologies, which has developed a product that can absorb impact and decrease acceleration from head collisions. Unequal’s technology, also found inside some football helmets, is a four-layer military-grade composite material that can block, disperse, and convert impact energy.
