From the manufacturer

Just like Marry Poppins’ famous bag, this thing will make you look like a magician when unloading it! (and like a G on the way there!)

Designed out of pure necessity after decades of traveling the world carrying a helmet, backpack and/or gearbag. We took advantage of the space your head normally occupies and filled it with a pouch to keep your stuff to keep this backpack at a normal size, but able to carry an extremely abnormal amount of gear..

The MP Helmet Backpack was designed around a full-face helmet, but has became our only choice for half-lid trail riding, travel, surfing, snowboarding, hunting, camping and even motocross. Its padded design and water-resistant materials also make it ideal for camera-gear.
