Hi-Tec has named Charles Willis to be its new outdoor creative director, replacing Hy Rosario, who is leaving the company to pursue other interests. Willis comes from Wolverine World Wide, where he was most recently Merrell group vice president and creative director. Separately, Hy Rosario, Hi-Tec’s global outdoor category director, is leaving the company, though company officials insist that there has been no reorganization of the outdoor department. Another official of Hi-Tec, Sara Coyle, has left the company to work in marketing at Stag, the British buying group.
