Sterling Rope IonR XEROS Rope

Yes, the 9.4 mm diameter strikes a great balance between durability and handling. It is thin enough to feed smoothly through most belay devices but thick enough to offer a secure, tactile feel that helps beginners gain confidence while clipping.

The UIAA Dry certification means the rope has passed rigorous testing to ensure it absorbs very little water when exposed to wet conditions. This is crucial for maintaining the rope's strength and preventing it from freezing or becoming heavy during alpine or ice climbing.

Yes, for lengths of 60 meters and longer, the IonR includes a middle mark. This is a critical safety feature that helps you quickly identify the center of the rope for rappels and transitions.

The 9.4 mm diameter is compatible with the vast majority of modern belay devices, including assisted-braking devices and standard tubes. However, always check your specific device's manufacturer guidelines to ensure it is rated for a 9.4 mm diameter.

XEROS is Sterling's dry treatment process that protects the rope from the inside out. By treating the core and sheath, it significantly improves the rope's longevity and performance in wet or abrasive environments.
