Black: 1 piece Navy: 1 piece [Thin and Soft Material] Made with a soft, exceptionally smooth fabric that gently wraps your head for a light wearing experience. It's useful not only in summer but also in spring as the temperature rises, and in early autumn when the temperature is still high. [Sweat Absorption, Quick Drying, Antibacterial, Deodorant] Cotton has excellent moisture absorption and breathability, so it quickly absorbs sweat, reduces stuffiness, prevents stickiness, and keeps your skin clean. [UV Cut & Cold Protection] With a maximum UV cut shielding rate of 99.9% and a UV protection index of UPF50+ (tested), it effectively blocks sunlight and protects your precious skin from UV rays. The fabric is double-layered, making it opaque and warm, so it protects you from the cold in air-conditioned rooms. [Stretchy & Hand Washable] Made with highly elastic material, it fits your head comfortably and can be worn loosely. You can enjoy fashion without stress, as it doesn't tighten your head even when worn for long periods. Note: When washing, please be sure to use a laundry net. [Unisex] Easy to use for all ages and genders. Recommended for various occasions, from short outings and walks to commuting, traveling, cycling, sports, and outdoor activities.
