A windbreaker outdoor jacket is a lightweight, wind-resistant outerwear piece designed for outdoor activities. Typically made from synthetic materials like nylon or polyester, it features a thin, breathable construction that helps block wind and light rain while allowing moisture to escape. Windbreakers are often packed with functional details, such as adjustable hoods, zippered pockets, and elastic cuffs, making them ideal for hiking, running, or casual outdoor adventures. With their compact and portable design, windbreakers are perfect for layering in unpredictable weather conditions, providing comfort and protection without the bulk.
