There's plenty to pick from: The global men's underwear market is expected to expand to $11 billion in 2020 from $8.4 billion in 2015, according to Persistence Market Research. That 31 percent jump dwarfs the expected 14 percent growth in the overall men's apparel market to $33 billion in 2020, according to Edited.
