I am doing freestyle-skiing for 4 years. I use body protection but I do not have a good experience with it. They are expensive and it takes more time to put it on.
For my graduation project on Design study I'm thinking about making a new sort of 'back-protection' what protects the important lumbar vertebrae (L1 t/m L5), that provides you can turn your body.
What do you think of my idea?
