Black Diamond Nylon Sewn Runners Blue, 120cm

There's no doubt you've seen Black Diamond's Nylon Sewn Runners on the mountains while climbing, tied to chickenheads, slung around trees, and bleached by the sun. That's because climbers trusted these smooth, colorful, and durable slings before colorful spandex was a thing in the vertical world. The question you have to ask yourself is, do you trust the old, manky runner already attached to the wall, or do you bring a spare to bail off of when the route gets too serious? We recommend the latter.
