Designed with input from Tiger Woods, Nike's Golf learning System for children retails as separate clubs, and comes with different sizes for different heights. The product range includes clubs, balls, bags, gloves and footwear and all clubs are made with steel heads and graphite shafts. The system is broken down into Par Red (for golfers under 50 inches tall), Birdie Blue (51-58 inches) and Eagle Silver (59-66 inches). Par Red starts with four clubs: driver, mid-iron, wedge and putter; Birdie Blue introduces a hybrid and Eagle Silver brings in a fairway wood and seven-iron.
