Victorinox has opened a public online vote to choose the best sustainable design submission to its "Time to Care" competition. The call for entries has been open since January 2011, and the seven best were chosen by jury in May. Throughout June, July, and August, the top seven designs are open to a public vote. The ultimate winner will be awarded prize money at a ceremony in October, and work with Victorinox to bring the design project to fruition.
