In the summer, I generally wear slighty baggy shorts made by Columbia with deep slash pockets. I could carry spare PMAGs in there if I wanted to.
They hold a spare mage just fine.
In the winter, generally I will wear a two cell magazine puch opposite of my gun and cover it the same as I do my pistol, with either an untuck shirt or a vest.
