From what material are harnesses and ropes typically made?

Harnesses and ropes used in rope access systems are primarily made from synthetic materials, with nylon being one of the most common choices. Nylon offers excellent strength-to-weight ratios, flexibility, and durability, making it ideal for the stresses and demands experienced during rope access work. Its ability to absorb shock and resist abrasion enhances safety and performance in high-risk environments.

While polyester is also a strong contender, often used in applications where lower stretch is required, nylon's overall performance under dynamic loads and its resistance to UV degradation make it the preferred choice for climbing and industrial use. Other materials like hemp and polypropylene do have historical significance and specific applications, but they do not match the performance characteristics and reliability needed for modern rope access techniques. Hemp, while strong, is less durable and more subject to environmental degradation, whereas polypropylene is lightweight and floats but lacks the strength and durability necessary for heavy-duty applications.
