Not the kind of day that I like to ride in on, 4C/39F and a bit rainy but not too much otherwise I wouldn't have ridden in (I don't have rain pants and at this temperature, a very rainy 20km/16mi ride would "freeze" me after 50-55 minutes of riding).
I do have a decent rain coat (below) that I'll wear on days like today where the visibility and light are low and it is rainy and cold (I bought it a bit oversized so there's plenty of room for layers underneath).
However, when I arrived at work today, I noticed another fellow come in on his bike, also in raingear but he had taken the opposite approach.
or, maybe he had gone duck hunting on the way in to work. Who knows why he would dress this way?
