Solid rope for very good price

Nice solid rope that coils well. Recently getting back into climbing outdoors and this rope gives the reassurance needed but is flexible also.

Great rope

Great rope that feeds through the grigri brilliantly and is light to transport. I bought a 70m and cut it in two for indoors.
