The folding bicycle helmet by Overade

Note:  This product is actively seeking funding on a European crowd-funding site called Ulule. Bicycle helmets are a necessity for safety but a pain when you're not actually riding your bike. When not being worn, Overade's folding helmet folds to reduce the volume of the helmet to a third of the original size for easy storage off the bike. Available in black or white, the helmet will be available in two sizes: S-M, for a head circumference of 54 to 58 cm, and XL, for a head circumference of 58 to 61 cm.
