【SUN PROTECTION】Engineered for beachgoers and outdoor travelers, this polyester fabric hat blocks 99% of UV rays covering your face during sunny seaside walks or garden sessions. 【ADJUSTABLE FIT】Featuring an integrated inner drawstring, this hat adjusts to fit head circumferences of 56-58 cm / 22.05"-22.83". The 13 cm / 5.12" depth offers a snug, secure fit that stays in place on breezy days. 【PONYTAIL OPENING】A rear bowknot features a clever neck opening, allowing you to comfortably wear high ponytails without pushing the brim forward, preventing neck pressure during busy daily commutes or outdoor walks. 【SHAPEABLE BRIM】Built-in memory wire inside the 10 cm / 3.94" brim lets you customize the arch. Easily flip the edge upward for a casual look or down for maximum shade during intense afternoon sun exposure. 【EASY MAINTENANCE】Crafted from quality polyester, this foldable accessory holds its shape after hand washing. Simply dry it naturally to maintain its smooth texture, making it an excellent packable choice for summer outings. Package list: 1x Hat
