This piece is made from a fabric blend of 83% Polyester, 8.5% Nylon, and 8.5% Acrylic, with a 250g weight that gives it a substantial, warm handle for the autumn/winter season. The polyester-rich blend supports the high color fastness and warmth-retaining properties noted for this piece, while the nylon and acrylic fibers contribute to the fabric's overall structure. The knit construction and plain solid-color finish suit the light mature casual aesthetic, making it a fitting choice for daily commute and relaxed casual wear. The piece also features anti-static and antibacterial functions, and its straight cut, polo collar, and long sleeves are designed for layering through autumn and winter. The 250g weight provides a balanced, ordinary thickness that works well for the cooler months without feeling overly heavy.
