I never use my back pockets, because sitting on wallets etc. isn’t good for the wallet’s longevity or your back. So for 20 years the only pants I’ve worn have been pleated khakis (or cargo shorts when really casual). You can put a bifold wallet and a cell phone into one front pocket, and a .32 Seecamp in a sleeve holster in the other.
Most khakis also have a little change pocket inside the right pocket. I have found that keys do the worst damage to one’s pockets, but not if they’re in the change pocket or in a little drawstring cloth bag like they sell tumbled gems and marbles in.
Unfortunately, pleats seem to be “out” now, at least for men, and can’t be found at the Gap, Old Navy or other mall stores. I can’t put much of anything in plain-front pants that otherwise fit right, without odd bulges and cloth stretched tight.
