Material: 100% Polyester Product Features: Offers warmth, structure, and reliable durability with practical pockets. Designed for multi-season versatility, making it suitable for wearing alone in spring and autumn, or as a layering piece in winter. Washing Instructions: Hand wash or gentle machine wash recommended using cold or warm water with a mild detergent. Avoid bleaching and direct exposure to high-temperature sunlight. For patterned styles, turn inside out before washing and do not iron directly on the printed design. Special Notes: The size data is measured with the garment laid flat. Due to different measurement methods, a margin of error within 1-2 cm is considered normal. When designing patterns, the font size should be no less than 8pt. Avoid overly delicate fonts or lines (such as fine Serif / Songti typefaces) to prevent the text from becoming illegible due to wear or printing limitations, and to prevent ultra-thin lines (<0.2mm) from fracturing.
