Being a keen mountain biker this design really caught my attention. Currently polystyrene shells are used which if we are being honest are pretty rubbish. They are hard, cold and the padding never fits. This design by Aniruda Surabhi, the Kranium Helmet, has an internal structure made from cardboard, however due to the structure is able to absorb 4 times more force than current polystyrene helmets. This I know seems pretty amazing. Also due to the material choice the helmet can be tailored for each individual user creating the perfect fit. The cardboard interior is covered with waterproof acrylic so it does not get wet. Some large manufacturers have already taken interest in this and I wonder when and where it will hit the high street. However there is one issue that I can see potentially being a problem. Unless the internal cardboard structure is waterproof, will it degrade due to sweat? Let’s be honest, anyone who rides frequently will know on a summer’s day you can literally ring out the pads in your helmet. Will cardboard be able to last in these conditions? Great design though!
