Stay comfortable while representing your favorite Nba team in this Boston Celtics Authentic Standard Issue Travel Performance Pullover Sweatshirt from Nike. Crafted with Dri-fit technology, this midweight pullover wicks away moisture to keep you dry on the move. The relaxed, boxy fit provides a loose and roomy feel across the chest, shoulders, and body, but the rib knit cuffs and hem help you move as freely as you want for the best of both worlds.
