There are two considerations in choosing how to dress for this course. First of all, our shop is in a poorly-insulated concrete block industrial building, and it gets cool and drafty in the winter time. Dress with a couple of warm layers, and for sure put on some warm socks. Secondly, this is a shop course and you'll be handling grease, oil, cutting fluid and so on. While our shop bikes have never been ridden, and have never been outside in the mud and dirt, it's still a shop environment. Be prepared to deal with the usual shop dirt and stains.
