I bought the extra small in red/black and I couldn't be happier with it.

I am a daily year-round bike commuter. Perfect size for tools. mini-pump, spare tube, lunch, phone, waterproofs. Will hold an 11x8" pad or folder, netbook, tablet whatever. Like all messenger style bags you can loosen the closure straps and carry something much bigger if you need to. I thought about the small but am glad I went with the XS. Does not resemble a woman's purse as I feared it might.

Fabric is stiff and resilient, and the details are very well thought out. Straps are angled just right, plenty of pockets. The bag has a stiffener in the back organizer which helps the bag keep its shape. Dangling reflectors and strap to hang lights. Even the color is a nicer than the photo, less orange, more cherry.

I fully expect this bag to outlive me. A steal at under $40. Buy one before they change their minds.
