This gilet requires no setup; it's ready to wear straight out of the package. It is highly compatible with a wide range of athletic and casual apparel. Pair it over long-sleeve shirts, hoodies, or light sweaters for added warmth. It can also be worn under a larger jacket for enhanced insulation. To ensure the longevity of your adidas 3 Stripes Down Gilet, care is essential. Always consult the specific care label inside the garment for the most accurate instructions. Generally, down-filled garments often require machine washing on a gentle cycle with a mild detergent, followed by tumble drying on a low heat setting with dryer balls (like tennis balls) to help fluff the down and prevent clumping. Avoid dry cleaning and using bleach. Store in a dry, well-ventilated area.
