adidas by Stella McCartney's water-repellent sweatshirt is proof that your workout gear can be just as fun and statement-making as the rest of your wardrobe. Decorated with black and white jacquard flowers, this style is loose fitting but defined by stretch-jersey trims at the high neck and hem. Wear it when running outdoors, unzipping the front for extra ventilation as things heat up. -- Black and white jacquard, black stretch-jersey - Zip fastening along back - 98% polyester, 2% elastane - Machine wash - Imported
