The piece is made from a cotton-blend fabric that combines 87% Cotton and 13% Polyester in the Heather Gray, Black, and Dark Gray colourways, while the Light Blue colourway uses 86% Cotton and 14% Polyester. This blend supports the relaxed, casual, and retro aesthetic of the piece, offering breathability, warmth, and resistance to deformation. The fabric has a weight of 380G and a yarn count of 51NM/2, making it suitable for autumn and winter wear. The inner fleece provides a soft, non-cold touch against the skin, and the loose fit allows for easy layering. The piece features a screen-printed nautical graphic that remains clear after repeated washing, and the ribbed cuffs and hem help maintain the shape and durability. It is designed for daily, sports, and casual occasions, fitting a preppy, ivy-style, and urban fashion look.
