You're not going camping, you are going professionally flying.
Stick with the flight bag.
Agree 411A, the only camping I have ever done was with the scouts or when I go to certain nightclubs....LOL
In one company I flew with one Captain came to work with no bag at all - his headest and licence/passport were in his hat - he said it was pointless bringing anything else! (this was before the days of "budget" airlines not serving food/drinks ect to flight crew!)
