This ventilated sun hat combines durable 75/25 poly/nylon ripstop construction with 100% polyester air mesh at the top and back of the crown to keep you cool and comfortable during outdoor adventures. No Fly Zone insect repellent technology and UPF 30 sun protection help block bugs and harmful rays, while an elongated rear brim provides extra coverage for the neck and shoulders. Comfort features include a moisture-wicking sweatband, an adjustable cord with toggle at the crown, and a secure chin drawcord for windy conditions. A foam brim keeps the hat afloat for water activities, and the robust ripstop fabric resists wear and tear for long-lasting performance. Specially treated products may be subject to additional requirements—please check local regulations—and a size chart is available online to ensure the best fit.
