It is a mesh storage pocket. The mesh design mainly helps improve breathability while also allowing you to carry lightweight essentials such as a phone, keys, or cards. It keeps small items easy to access and helps release heat through the mesh structure, reducing stuffiness around the chest area.

It uses yarn-level sun protection, meaning the UV-blocking elements are woven directly into the yarn rather than added as a surface coating. Because of this, repeated washing, friction, and sweating will not easily reduce the sun-protection effect, making it long-lasting and durable. Many regular sun-protective shirts rely on coating-based protection, which may lose effectiveness after several washes.

UPF 100+ means that less than 1/100 of UV rays can pass through the fabric, blocking more than 99% of ultraviolet radiation. It provides more comprehensive protection in high-exposure environments such as plateaus, beaches, and long periods of direct sunlight.

The high collar is made with lightweight and soft fabric. During normal head movement or turning, it should not create a noticeable tight or restrictive feeling around the neck.

Although yarn-dyed fabric generally has good colorfastness, slight floating color may still come off during the first wash or after long-term use. If washed together with white, beige, or other light-colored clothing, this floating color may transfer onto lighter fabrics. It is recommended to wash it separately or with similar dark colors, using cold water and a neutral detergent.
