I've used it a few times, but there are only a few loose threads, and no noticeable stains. (Please refer to the photos.) It may be compressed for packaging. +++++++ Product Information: Sleepy Pile sleeping vest. When worn over baby clothes or pajamas, it prevents chills during sleep and upon waking. It features three large bear appliqués and opens with snaps in the front for easy on and off. Sleepy Pile: High-quality cotton yarn is used for the part that touches the baby's skin, and a special twisted nylon yarn is woven between the cotton yarns, achieving the unique "stretchability," "moisture absorption and breathability," and "feel" of Sleepy Pile. It is also resistant to washing, dries easily, and does not lose its shape or wrinkle easily. Size: 60-90cm (approx. 3 months to 2 years old) #familiar #familiar #sleepingvest #sleeper
