Did you know that one in four people worldwide are physically inactive? Buying just one shirt can help change this. For every BOKS Giveback T-shirt sold, Reebok will donate $18 to BOKS, a free physical activity program that improves our children physically, mentally and socially by strengthening their minds and bodies through movement. To learn more about BOKS visit www.bokskids.org. Offer available while supplies last.
