Appropriate outerwear for temperatures around 40F (4C) balances warmth and comfort. A medium-weight jacket, such as a fleece, softshell, or quilted style, often suffices for these conditions. Layering thinner garments underneath allows for adaptability to fluctuating temperatures. Supplemental protection against wind and precipitation might include a light, water-resistant outer shell.
Choosing suitable attire for cool temperatures is essential for maintaining core body temperature and preventing cold-related illnesses. Historically, humans have utilized various materials and garment designs for warmth, evolving from animal hides and woven fabrics to modern synthetic, insulated materials. The development of weather-resistant and breathable fabrics has significantly improved comfort and protection in varying climates.
