Helmets are a necessary part of cycling safety, but they can be bulky and cumbersome. Not a problem for racers, but a big inconvenience for the urban cyclist. The Dahon Pango, developed with Pulsium, is an ultra-compact, fully safety-certified helmet that packs away to store easily inside a bag or backpack. Utilizing a patented, intersecting spline design, the Pango folds to less than 1/2 of the size of a regular helmet and adjusts to comfortably fit a wide range of head sizes. It also features swappable panels that adapt to weather (rain) or fashion. Styled for urban riding, the Pango eliminates one of the last excuses to not wear a helmet.
