The North Key Fishing Shirt is made from the highest-grade, moisture-wicking performance fabric that protects you from the sun and has specially cut vents to keep you cool and dry while you're out on the water. Its lightweight design ensures comfort and flexibility all day long. If it get's warm, roll up your sleeves and use our buttoned sleeve fastener to keep them taut. Double barrel reinforced seams and bar tacks make sure this shirt stays wearable for years to come. One feature we enjoy and use frequently is the sunglass cleaner that's attached at the bottom hem to clean your sunglasses safely.
