Rope Logic is offering an improved version of the popular Bee-Line. Made with Technora-black, these eye tails feature a para-aramid fiber with high tensile strength, high modulus and excellent resistance to heat and chemicals. It has been solution dyed – which ensures the color reaches right to the core of each filament, giving it a deep black color, and the added bonus of increased UV resistance. As a filament yarn, Technora has proven its superior properties in our climbing prusiks. 100% Vectran fiber core, 75% black Technora cover, and 25% black filament polyester cover.
