An essential part of any alpine climber's rack, Black Diamond Dynex Runners are indispensable for building anchors, slinging natural features or extending placements to reduce rope drag. This highly abrasion-resistant, lightweight material won't weigh you down and absorbs less water than nylon, making it perfect for big routes and snowy or icy terrain. Each size is also color-coded for quick and easy identification on your harness.
