In order of acquisition:
- Racktime City bag for books etc
- Cannondale Grocery pannier (used for clothes in warmer / drier months)
- Axiom trunk bag (for weekend rides)
- Bontrager Urban Commuter set (have been using 1 for clothes / extra winter gear)

I'm not really a fan of the Bontrager set. The quick release mechanism is nice, but most of the pockets are so tight its difficult to use them for storage. The lids always flop over and can't stay open on their own which can be frustrating while loading / unloading.
