The proven Element Key-Lock Express Sets from Mammut are now equipped with Indicator wear technology. The robust polyamide sheath is of a different colour from the red core. If the sling is damaged, the red core shows through, telling the user that it is imperative to replace the equipment. The two high quality key-lock biners are designed not to snag when clipping and are amazingly lightweight. Availible in Straight/Bent and Straight/Wire gates.
