The Yale Blue Tongue represents a quantum leap in tree climbing line technology. This climbing rope is made from premium grade polyester and has been made for exceptional performance through mechanical ascent/descent devices as well as the traditional Arborist climbing techniques.

The 11.7mm diameter provides the perfect balance between the weight of 11mm line and the feel of 12.6mm line. The highly vibrant colour guarantees exceptional visibility in the tree. It is possibly the most vibrant and visible rope on the market.
