I ride in my bike clothes and carry my street clothes to the office along with a tall kitchen draw-string trash bag and two sandwich bags in my backpack which I carry on my back rack. When it starts raining I cover my backpack with the trash bag with the drawstrings towards the bottom. I put my phone in one sandwich bag, and sometime use the second bag on my seat. Yes, I get wet, but I found I smell better wet from rain than I do wet from sweat.
