Invented by two Swedish women, the Hövding bike helmet keeps fashion-conscious cyclists safe without compromising their appearance. Designed to inflate over your head in the case of an accident, the “helmet” takes the form of a collar during regular use. Sitting around the neck, it’s intended to blend in to clothing and prevent the oft-feared fashion faux-pas: helmet hair.

Underneath the collar is the airbag, which will balloon up around the rider’s head if it senses a crash, powered by a helium gas inflator. It uses rechargeable battery-powered sensors to detect abnormal, crash-like movement and then sends a signal to the inflator, which launches the giant puffy hood made of nylon and able to survive contact with concrete. It acts quickly in the case of an emergency by inflating in .1 seconds and is designed to withstand multiple impacts before it deflates.
