As far as bulk boxers go, these are the ones to go with. They fit snug in the right places and leave room where room needs to be. My favorite "boxer" by far is CK Micro Model, but those are expensive and not  something I wear for every day juggling routines. These however are great for workouts and day-to-day wear.

UPDATE: The light blue is a horrible color, the darks look better. They have gotten quite a bit faded in 6 months of use, but that doesn't really bother me. They are also a bit saggy, but I guess I could be losing weight. The point I'm trying to make here is that I am incredibly good looking.
