    This product is for…

    Climbers who want ultralight, always-on-harness cord for anchor building, rappel extensions, and rescue systems. Different lengths suit different roles: short (120cm) for rappel extension/tether, mid (180cm) for quad anchors, long (240cm) for anchors and rescue scenarios.

    Worth noting…

    One host notes it fills the gap left by discontinued Edelrid Aramid Cord and considers it an improvement. Notes are uniformly positive with no criticism or fit/durability caveats raised.
