The piece is made from a fabric blend of 68% cotton, 29% polyester, and 3% spandex, giving it a soft, breathable feel with a touch of stretch for comfortable, relaxed wear. The standard fit and regular thickness make it suitable for casual, everyday layering, while the Korean-style aesthetic and raglan sleeve design support an easy, laid-back look. The fabric is a single blend used throughout the piece, with no separate lining or filling. The cotton-rich content keeps it comfortable against the skin, the polyester adds durability, and the spandex provides flexibility for movement. The regular thickness makes it appropriate for casual wear across seasons, and the pull-on raglan construction with elastic hem supports a relaxed, sporty-casual style.
