Most tennis polos stand up straight, tuck in, and wait to be told what club they belong to. The DoubleSwan AirMesh Polo has a relaxed drop shoulder, a baggy sleeve, and an embroidered mark that puts two players across the net inside a heart. It is still a proper polo. It has simply stopped pretending the match is the only interesting part of the day. Wear it for the warm-up, the set, and whatever happens after nobody wants to go home.
