Built for the table. The Sport Collar is the shirt that keeps up with a full day of matches: an ultra-lightweight performance blend that doesn't shrink, doesn't fade and holds its shape and colour wash after wash. The stand-up collar and quarter-zip keep the look sharp for walk-ons and presentations, while four-way stretch and moisture-wicking, cool-touch fabric keep you comfortable from the first rack to the last.
