This jacket is designed for adult males and is specifically an XXL size with a regular fit, ensuring compatibility with a wide range of body types for comfortable wear and layering. There is no specific setup required; simply put it on and adjust it to your comfort. For care, always refer to the garment's label. The recommended care instructions are to machine wash cold. It is important to tumble dry low to preserve the fabric and maintain the jacket's shape. To extend the life of your jacket, avoid using harsh detergents or bleach, especially with a white garment, as these can cause discoloration or damage to the material and water-repellent finish. Close all zippers and fasteners before washing to prevent snagging.
