Lightweight and sun shielding, our Trim Brim Hat is made with fast-drying 4-ply SUPPLEX recycled nylon with 50+ UPF sun protection and a DWR (durable water repellent) finish. This sun hat has an adjustable cinch on the crown and a flat drawcord chin strap with a soft-lock adjustment that cinches without chafing. Internal headband wicks moisture; ventilation holes for comfort. True to the trim in its name, this hat packs small for easy travel. Fair Trade Certified sewn.
