Argos soft pilot case item 285/8542 - £24.99 I keep in car/home office with my instructor and examiner notes / paperwork and Pooleys etc.. I then have a soft USAF style military helment bag with stuff for flight like plates, map, headset, spare specs etc.. Treat those going about carrier bags or why do you need anything at all to go flying with a pinch of salt - it is quite sensible to get something to keep essential kit in, just keep it light and to the minimum needed.
