Jackets are outer garments worn over other clothes to provide warmth, protection, and a professional appearance in various settings. In the culinary world, chef jackets are designed to be durable, comfortable, and often feature double-breasted fronts, long sleeves, and heat-resistant buttons. They are typically made from breathable, easy-to-clean fabrics like cotton or polyester blends. Chef jackets also help maintain hygiene by covering personal clothing and providing a barrier against spills and splashes.
