The 9.9 Gym Workhorse Classic is a hard-wearing single rope for all-round use, and the most durable rope Mammut make. While it's designed for redpointing and working routes indoors, it can be used outside too. It has a 9.9mm diameter with a minimal weight.
It is part of Mammut's overhauled rope range and is demonstrating its strong eco-credentials.
This classic version is untreated for great value, but for maximum toughness the dry edition has the core and sheath treated to massively improve durability and prevent water ingress. If you're looking for a similar rope in longer lengths check out the .
