These pants from Amazon have 2 additional pockets to conceal ammunition clips--or chips. Although they're accessible without taking your pants off during a strategic potty break, they're very unnoticeable. Hell I even have difficulty locating them! My anecdotal evidence suggests that you can carry about 100-150 chips without waddling like a duck.

P.S. I'm a Second Amendment (pants) fanatic!
