A life vest, also known as a life jacket or personal flotation device (PFD), is a safety garment designed to keep a person afloat in water. Made from buoyant materials, life vests are essential for activities like boating, swimming, and water sports. They come in various styles and sizes to accommodate different ages and body types, ensuring that everyone can find a suitable option. Wearing a life vest significantly increases the chances of survival in emergencies, such as capsizing or falling overboard. Many life vests are equipped with reflective strips and bright colors for visibility, making it easier for rescuers to locate individuals in distress. Proper use and maintenance of life vests are crucial for ensuring their effectiveness.
