Description: A true 11.7mm diameter 24 strand climbing line that combines the lightweight characteristics of 11mm ropes and the more conventional sizing closer to that of a 1/2" climbing line. Blue Moon incorporates Yale's 24 strand 'Tite-Braid' cover that virtually eliminates cover milking. The braided filament polyester core creates a firm rope that provides superior working-flex service life without work hardening.
