A bandana held rearview mirror.
Barrier This Solves
A rearview mirror is a very useful safety and comfort tool for cycling in traffic (car traffic and even cycling traffic!), and the head mounted ones have several advantages over the bike mounted ones, but they require the use of either a helmet or glasses, as support. This cyclehack enables us to use a head mounted mirror without a helmet and withou glasses, making the solution available to more people, with different personal preferences.
