The fabric weighs 210-220g and has a standard thickness, giving the piece a relaxed, youthful feel that fits the retro aesthetic and casual occasions. The piece features a lapel design, short sleeves, and a crew neck, with a gradient print and letter pattern that add to its vintage sport style. The fabric's quick-dry and moisture-wicking properties help keep you comfortable during daily wear and light sports, while the UV protection adds coverage for sunny days.
