Material Composition: 100% Polyester About this product: 【Perfect for Outdoors】This hat provides all-around sun protection for your face and neck. It's suitable for everyday use like commuting, going to school, and traveling, as well as outdoor activities such as farming, gardening, fishing, hiking, and sports days, where you have to stand in the strong sun for long periods. 【UV Protection】Excellent breathability and UV-cut effect protect not only your face but also your neck from UV rays! A hat is essential in summer. The wide brim blocks out UV rays, fully protecting your face and making you look even cuter. Wide-brimmed hats also have a face-slimming effect. 【With Chin Strap】The combination of a chin strap and a hat is very convenient when riding a bicycle or walking on a windy day. By hooking the hooks on both ends of the string to the loops inside the hat, the hat is securely fixed, so you can use it with peace of mind without worrying about it being blown away by the wind! 【Comfortable and Refreshing to Wear】This wide-brimmed hat uses high-quality materials with excellent absorbency and quick-drying properties, so you won't feel uncomfortable even after wearing it for a long time. The breathable fabric on the underside absorbs sweat and prevents stuffiness when worn outdoors in the summer. 【Wrinkle-Free, Foldable, and Lightweight】Our women's hats can be folded without wrinkling and can be worn in a beautiful shape. The silhouette is also beautiful and doesn't lose its shape. When not in use, it can be folded up small and put in your bag, making it a convenient UV-cut hat to carry around. ＜Size＞ Head Circumference: 54cm - 60cm Hat Brim: 13.5cm When shipping, we will fold it compactly (and in some cases compress it). Please understand about wrinkles.
