Lots of 2 to 3 day regional jet travel. Setting up for one bag with Tristar as primary bag. Carry phone, iPad & accessories plus printed material about 2 inches thick. Men's Executive dress clothes plus jeans and casual shirt. Extra shoes. Would like reccomendations for a professional briefcase that can fit in the mid section of the Tristar and then be taken out for use in presentation or scoping meetings. Thoughts, ideas?
