I'm writing this as a dyed-in-the-wool boxer guy - was born wearing them. Recently had hernia surgery and the medical people recommended I wear briefs immediately after the out-patient surgery and for a period afterward. A friend who knew my dislike of skimpy underwear suggested these Papi low-rise briefs so I got a few pairs. To my amazement they're comfortable, roomy yet provide ample support and are light as a feather. I use them now primarily under gym shorts for the beach and for exercise.  Papi makes another variation on this product called Key Hole briefs and I highly recommend them as well for every-day work and casual wear. In a nut shell: size matters and these briefs are comfortable, roomy and non-binding.
