The blue clay Caja Mágica Courts at the Mutua Madrid Open came and went with 2012, as did the coordinating blue and white color scheme worn by fan favorite Roger Federer when he defeated Tomas Berdych for the title. This year Federer returns to the European Clay Court in a more laid-back look, foregoing the traditional formula of tennis polo + shorts for easy pieces that promise the ultimate in comfort and performance. But don’t misconstrue his low-stress dressing as staid; colors such as Poison Green, Light Steel, and Tourmaline in fabrics constructed with the latest in Nike apparel technology prove that comfortable can still be style-conscious.
