A fleece jacket is a type of outerwear made from synthetic materials, primarily polyester. It is known for its soft texture, lightweight nature, and excellent insulation properties, making it a popular choice for outdoor activities and casual wear. Fleece jackets are often used in layering systems, providing warmth without adding significant bulk. These jackets come in various styles, colors, and thicknesses, catering to different weather conditions and personal preferences. Many fleece jackets feature zippered pockets and adjustable cuffs, enhancing their functionality. They are also easy to care for, as they are machine washable and quick-drying, making them ideal for everyday use and adventures in nature.
