The Olympos walker from Topro is the "big brother" of the Troja, designed specifically for people who want to use their Topro walker outside on rough terrain as well as inside. It is available in two sizes, Small or Medium (please see details below regarding size recommendations). The Medium comes in a Dark Grey colour and the Small in a Silver colour. The Olympos on its own is a fantastic walker but the range of accessories makes it stand head and shoulders above the competition from similar styled walkers.
