If you are looking for an eco-friendly headwear piece, New Era and Major League Baseball have a batch of hats for you to choose from. Check out the MLB Repreve 59Fifty Fitted Cap Collection. They made only a few for selected league teams, such as the Washington Nationals, Houston Astros, and LA Dodgers. The dome and uppervisor of this hat are both constructed using a white Repreve fabric, which is made from recycled materials. The front embroidery is the current cap insignia for the designated team. They then provided some contrast by using a black uppervisor for the bill. Embroidered on the left panel in white is the New Era Flag, while the MLB Batterman logo at the back is in its full red, white and blue colors. Grab one here.
