Project your hardest routes with the Mammut Crag Indicator Wire Express Quickdraw. Its smart Indicator sling features a red core fiber that, in the event of damage, is easily visible, letting you know it's time to replace the sling. The rope-side carabiner has a wire gate to keep weight low and make clipping seamless, while the straight bolt-side gate and keylock nose make your post-send clean a breeze.
