Shock cord, also known as bungee cord, is a flexible elastic material typically made from rubber or latex, encased in a woven nylon or polyester sheath. It is designed to stretch and return to its original shape, making it ideal for various applications, such as securing items, providing tension, or absorbing shock. Commonly used in outdoor gear, such as tents and backpacks, shock cord is also found in sports equipment and automotive applications. Its ability to stretch and compress allows it to effectively manage loads and reduce the impact of sudden forces, enhancing safety and performance in many scenarios.
