The piece is made with a 100% cotton fabric weighing 225g, giving it a substantial yet breathable feel that suits the relaxed, casual, and retro-inspired aesthetic of the design. The washed and distressed finish works naturally with the cotton base, creating a matte, textured surface that supports the piece's utilitarian, functional style and makes it an easy choice for autumn/winter layering. The ribbed stripe is a 58% cotton, 42% polyester composite elastic fiber blend at 285g, providing structured stretch and recovery where it is used. Together, the cotton body and the ribbed elastic blend make the piece suitable for everyday casual wear and for building layered looks within a functional, retro wardrobe.
