Introducing the LTM5 Airflo Hat, a large hat with the small brim. It's got all the features you'd expect from an Airflo, including our signature mesh for staying cool, water resistance, and UPF 50+ sun protection. And let's not forget its bobber-like buoyancy on water. But don't let its sleek profile fool you, this hat still stands out in a crowd. Brim measurements: Front: 2 5/8", Back: 2 3/4", Sides: 2 1/8".
