If you know a man who is a big fan of Superman, a great gift could be some underwear that features the iconic “S” logo. Some of these are designed with a little cape in the back. This, I assume, would make them somewhat bulky to wear under a pair of pants. But the point here isn’t comfort, but rather originality and fun. Look for socks that also feature a cape as another great present.
I find the ones with the cape cute and funny:
