Reflective materials are just one aspect of safety jackets. Depending on the specific type of jacket, there may be a variety of additional protective features included. Many safety jackets are constructed from durable, weather-resistant materials to shield the wearer from environmental hazards. 

For example, some jackets are made with waterproof fabrics for rainy conditions, insulating materials for cold weather, or even flame-resistant fabrics for workers exposed to fire hazards. 

In addition, safety jackets often incorporate practical features designed to enhance both worker safety and efficiency. These features can include adjustable cuffs and hems for a secure fit, pockets for storing essential tools, and built-in harnesses for fall protection. 

In conclusion, safety jackets combine high-visibility design with protective elements, creating a wearable tool that helps keep workers safe in various conditions. While the specific features may vary based on the type of jacket and the intended industry, the ultimate goal remains the same: to protect the wearer while enhancing visibility in the workplace.
