A friend of mine sent a link to Rayon Jaune (in French), a new company north of Lyon, near the Swiss border, which offers these wonderful reflective scarves. As seen above, the idea is that there is a "normal" side one wears in town, and a reflective side that's meant for while one is on a bike.
The leaf print shown above is my favorite.
This dot option is my second-favorite, that's pretty wonderful.
However, I'm not sure either of them compare to these dragon vests, which may be my favorite safety-gear yet. Is it wrong to want a grown-up sized dragon safety vest? Yes, I'm a nerd.
