maybe you could slip in one of those cig style one hitters maybe eh? or fuck it, just any kind of small lil one hitter in there would be rad. anyone remember the 420 pack burton put out a few years ago? that thing was so legit. it had a built in collapsable chair, a whole lil daily planner which had elastic straps for all the smoking needs, different compartments inside for diff beverages and also came along with its own flask...fuckin MONEY. pretty sure you could only get those by knowing a local disctributor or rep or some deal though.
