High-grade RED webbing means it is both high-visibility and will last for years even with UV exposure. The internal bungee absorbs the shock-load when having to release your grip on the bar under load. The Loop/Loop short line on the harness-end clip allows you to be able to Larkshead the leash onto your harness in the event that the clip doesn’t work well for your harness. Finally, removable stainless steel clips on both ends means you can replace them if their spring or action wears out over time. Many leashes have clips stitched in which means if the clip goes bad, you’re buying a whole new leash.
