Are we done with this? I've seen people with closets full of commuter gear and people who could fit all their gear in a 10L bag. We aren't on the north face here - this is a 10 mile commute. Get yourself some blinky lights, a hi-viz sash use the backpack in your closet, then ride your butt into work. You will discover which items you really need later on and not be left with a closet full of junk - the only way to discover what gear you truly need is to experiment and conclude you need it. Just do it!
