Yomna Khallaf, 20, said shortly before the athletes headed to London, the committee gave them "funny things," Egypt Independent reported Wednesday.
"I wear X-small but they gave me Nike gear that was size double X-large," she told Cairo Stadium Radio.
"They gave us a bag that has a Nike logo on the front, but the zipper has the logo of Adidas," Khallaf said. "We had to buy $2,800 worth of real things from Nike for the team to look good."
Nike released a statement in response to Khallaf's complaint saying, "Nike is highly concerned that if these allegations are true, the athletes will have received products that do not meet Nike's quality standards. Nike's authorized distributor in Egypt has sent two official communications to the EOC on this issue and no response has been received."
