This was owned by my father, who loves mountain climbing, so I don't know the details. I believe it's a climbing rope, but please check the images and purchase accordingly. I don't know the manufacturer, but all the outdoor items I'm selling are my father's, and he liked high-end brands like mont-bell, so I think he bought this product from a reputable shop. Both ends have a core, starting from about 2cm in. It's clean with no visible stains, so the condition is quite good. 6m
