Haystacks and chutes. Zip lines and slides. When they come out the other side, we make sure they still have their hats. Lightweight and sun shielding, the hat is made of fast-drying 100% 3-ply Supplex nylon with a DWR (durable water repellent) finish and 50+ UPF sun protection. Incredibly fun-minded, this boys sun hat has an adjustable cinch on the crown and a flat, removable drawcord chin strap with a soft-lock adjustment that cinches without chafing. Reinforced front brim retains its shape, even when wet. Hat packs small for easy travel.
