Flight Bag PLC Sport w/Shoulder Strap by MyGoFlight
Finally found a quality bag the right size..
I've tried them all, either too big, too small, poor quality, too few pockets, too many, too soft, etc. This one is the right size, stands up nicely, not too many pockets to search through but enough to stay organized. High quality, looks great and shoulders easily (I don't like backpacks). Carries enough for everyday flying and short trips which is what most of us do anyway. Perfect bag for a CFI.
