This is a Lululemon Race to Pace 2.0 Black Adjustable Baseball Hat. One size fits all. The fabric tag has been removed, however I still have tag as seen in photos. A little shade goes a long way when we're logging kilometres under the sun. We designed this run hat with lightweight, sweat-wicking Swift fabric to protect us from strong rays with no extra bulk. Now we can go out and feel the burn without burning up.
