The Plixi helmet is kind of like origami, if origami were made from ABS and expanded polystrene and could save you from massive head trauma. So I guess in a way it's better than origami. From Paris-based Overade, the protective headwear for cyclists, skateboarders, and scooterers has a patented folding mechanism that allows users--and particularly commuters--to reduce their Plixis' size threefold, and then easily tuck them away in a bag or drawer at the end of a ride. Overade hopes this decrease in bulk and, in turn, hassle Plixi offers will encourage urban commuters to be more diligent about wearing a helmet.
As demonstrated in the above video, Plixi helmets can be folded and unfolded in a few seconds. When worn properly they provide the same level of protection as a traditional bike helmet, and comply with Europe's EN1078 safety standards for bicycle, rollerblade, kick scooter, and skateboard head protection. A compacted Plixi helmet measures 8.3" x 4.3" x 6.3". Weight is 17.3 ounces.
Plixis come in sizes S/M and L/XL, as well as colors black and white. Packages also come with interior fitting pads of various thicknesses to adjust helmets to individual levels of security and comfort.
