    Expert Review

    For anchor building, I really like having a 120cm and 180cm sling available. I used to love Edelrid's Aramid Cord, but it is no longer in production. Black Diamond has filled that hole in the market and made it even better by replacing the bartack with a splice.

    This product is for…

    Climbers who want a lightweight, always-on-harness cord for rappel extensions, anchor building, load transfers, and rescue systems. Different lengths suit different tasks: short/120cm for rappel extension or tether, 180cm for quad anchors, and longer for rescue or full anchor setups.

    Worth noting…

    Available in at least three sizes; hosts recommend owning multiple lengths for different purposes rather than relying on one. The spliced construction (no bartack) is called out as a meaningful design improvement over comparable products.
