>low profile pockets
Maybe the most simple is like the back pocket on a pair of jeans.

Another idea for 'low profile' is a seam pocket. Sometimes called 'invisible zipper pocket', etc. Quite common on dresses.

Another one I like is an 'inverted pleat pocket'. Still pretty low profile, but you can put chunkier things in it vs a jeans pocket. That's what's in the pic. Some guy's jacket at my old job, where I copped the idea.
