The Tracksmith Women's Twilight Tee is perfect for high performance on a warm day. This shirt has a silky, ultralight micro-mesh that wicks moisture and feels cool on the skin. While light enough for fast runs, subtle reinforced double stitching makes it durable enough to handle many wears. With freedom of movement and a barely-there feel, the Twilight Tee lets you focus on your speed while keeping you cool.
