    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.
