When in France recently I rarely saw a bicycle helmet, ce n’est pas chic. But designers Caroline Journaux & Adrien Guerin are working on one that can fold up and be put away in your pocket or purse. That makes a lot of sense if you ride a Vélo bike in Paris, since you only have a bike when you need it and would otherwise be carrying a helmet around a lot. I don’t know if it would pass a Snell test but I like the idea….
