Lightweight jackets are versatile outerwear designed to provide comfort and protection without the bulk of heavier coats. They are typically made from materials like nylon or polyester, which are both breathable and water-resistant. These jackets are ideal for transitional weather, offering just enough warmth for cool days or evenings. Many lightweight jackets feature adjustable hoods, pockets, and zippers for added functionality. They come in various styles, including windbreakers, rain jackets, and packable jackets, making them suitable for outdoor activities like hiking or casual wear. Their compact design allows for easy storage in bags or backpacks.
