Falling while wearing the Ski Mojo is usually no different than if you fell without one. As the Ski Mojo runs down the side of your leg it works as side impact protection bars, just like those on a car and will often reduce the affect of any impact. However, under certain circumstances: e.g. if you fall on the end of the upper telescopic rod, it may cause bruising (in the same way as if you fell on your keys if you had them in your pocket. There is a layer of Neoprene between your leg and the rod, which can usually be folded over and “doubled-up”; you may wish to add additional padding to fit between these rods and your legs to further help reduce the risk of bruising.
If you fall or are hit by another skier/boarder from the side then the Ski Mojo will take the majority of the impact rather than your leg. It will spread the impact down the length of the Ski Mojo which has the effect of cushioning any impact you receive. If you were not wearing the Ski Mojo, then any impact would be felt directly on the side of your leg.
We cannot make any claims that the Ski Mojo is impact safety equipment. The above is based on the anecdotal evidence of several Ski Mojo users. The most relevant anecdotal evidence is that we have not heard of a single injury (other than normal bumps and bruises) sustained by a Ski Mojo user other than in circumstances where they fell that the injury would have been worse if they had not been wearing their Ski Mojo.
