Trunk bag, roll my trousers, underwear and socks are just chucked in beside my trousers then shirt is folded on top.

I usually carry some food (crisps, chocolate, croissants and fruit) on top of my shirt.

Before this I used a pannier with an eagle creek folder in it which worked quite well, but I far prefer the feeling of a trunk bag on my bike. I also have used a backpack with an eagle creek folder but I don't like a sweaty back!

We have shampoo etc. at work so that isn't an issue, I don't brush my hair so that is ok too! We also have towels etc. (have a gym at work). I don't carry a wet weather jacket unless rain is forecast, if it is and it isn't required in the morning I will roll it and stuff it in the bungee cord at the top of my trunk bag. I don't need a jacket at work, but I have folded this up in the trunk bag before, I just use the expander section to make it bigger. I have also carried shoes in there (normally just leave a pair at work).

I have a tool kit, spare tube and 3 lights in my bag. The trunk bag is a topeak DX or something.
