The LTM5 AIRFLO® Hat "My new LT5 is the best-looking, best wearing, best proportioned hat in my collection of some 30+ golf hats. The LT5 was my standard headgear in Florida for ten days in early January while playing in a golf tournament. What a great hat! The turned down brim was perfect to keep the sun from my face and neck." Dave Reid, Master Teaching Professional.
