Tailored for top level sport climbing, the Stinger's intermediate rope diameter as well as the Unicore process makes it versatile even on alpine terrain.
The Stinger is made with Unicore, an astonishing process where the sheath and core are bonded without affecting the rope’s suppleness. If the sheath is cut or torn, the core and sheath remain bonded together, greatly increasing the safety margin of the rope. Check out the video for more info on this amazing feature.
The Stinger features Golden Dry treatment, where both the sheath and the core are dry treated. This way the rope has an astonishing water impermeability and incredible durability. In 2012 the UIAA adopted a new requirement for hydrophobic ropes that is now in full force. In this test a rope is subjected to light abrasion and soaked for 15 minutes. The amount of absorbed water must not be greater than 5% of the sample's weight. Beal's Golden Dry ropes easily qualify as "UIAA Water Repellent." A non-treated rope absorbs between 40% and 50% of its weight in water.
