Ultralight, Durable Sling.

The Black Diamond 10mm Dynex Runner is a lightweight, abrasion-resistant sling designed for alpine, trad, and ice climbing. Made from 10mm-wide Dynex, it offers a high strength-to-weight ratio with minimal water absorption. Indispensable for building anchors, slinging natural features or extending placements to reduce rope drag. Its ultra-strong yet supple construction ensures easy handling while maintaining durability in harsh conditions. Each size is also color-coded for quick and easy identification on your harness. A must-have for climbers who demand reliability without excess weight.
