Slacklining refers to the use of webbing tensioned between two anchor points to balance and walk. Slacklining resembles slack rope walking and tightrope walking as the line is held under tension. Slacklines differ from tightwires and tightropes in that they are tensioned to create a dynamic line with stretch and bounce like a long and narrow trampoline. Tension can be adjusted to suit the user, and different webbing can be used for a variety of tricks. The line itself is flat. Slacklining is popular due to its simplicity and versatility. It can be used in various environments.
