The Aerios Bucket Hat from Arcteryx is your extremely lightweight sun protection for summer and travel. The bucket-shaped hat provides shade for your head and is made from a very fine and quick-drying Airshell nylon double fabric. On hot days, moisture is efficiently transported away while ensuring optimal air circulation. Additionally, the outer material is lightly water-repellent due to a PFC-free treatment—perfect for when a few drops might fall or if you find yourself in the fine mist of an impressive waterfall. The Aerios Bucket Hat offers 360-degree sun protection, keeping your head well-shaded at all times. The underside of the brim features flexible Spacermesh TM for structure and shape, allowing you to easily reshape it and pack the Aerios Bucket Hat down to a very small size. It takes up almost no space in your travel luggage, and its weight of just over 30 grams is unbeatable. With a one-handed adjustable drawstring, you can quickly adjust the fit of the sun hat on the go.
