The piece is made from a fabric blend of 47.3% Modal, 45.9% Cotton, and 6.8% Spandex, with a fabric weight of 150g. The Modal fibers provide a smooth, soft touch with natural luster and good color fastness, while the Cotton adds breathable support and the Spandex delivers moderate stretch for flexible, comfortable wear. This combination makes the piece suitable for relaxed, casual wear in autumn and winter, whether worn on its own or as a layering base. The fabric has a cool-to-the-touch feel with a cooling value of 0.24, certified under GB/T 35263-2017. It is lightweight, soft, skin-friendly, and breathable, with stable shape retention and resistance to fading. The piece features a loose fit, regular sleeves, crew neckline, and solid color design, with reinforced shoulder seams and three-needle stitching at the neckline, cuffs, and hem for durability and shape stability. It is available in sizes S through XXL and in colors including heather grey, deep iron red, fitness blue, smoky purple brown, Paris grey, rich reactive black, grey white, and miu-style blue.
