There are a number of considerations that go along with wearing a packer. Choosing the right shape and size is obviously part of the process, but once you've made those initial choices, you'll need to decide what position makes you feel most comfortable. Remember that it may change depending on the circumstances, or even on the clothing you wear with it. Some people wear a packer for themselves, and don't necessarily want the rest of the world to notice it. Others are looking for a definitive projection. As with so many things, learning and experimentation are the keys to discovering what works for you.
