WIRED – This Clever Bike Helmet Collapses to Fit in Your Backpack

Closca’s full-size bike helmet collapses down into a flat disk that’s easy to fit into a backpack.

BIKE HELMETS COME in an abundance of shapes, but most of them are essentially identical in function. Maybe the arrangement of the vents or the fit of the straps differ between models, but they’re almost always just a rigid bucket you wear to protect your dome. Helmets certainly don’t disassemble or break down for easy storage.

But hey, this one does. Closca’s Fuga bike helmet is made up of three molded foam sections, all arranged concentrically. Push down on the center piece at the top, and the five-inch-tall helmet collapses into a flat disk 2.36 inches in height.
