The boxer brief part of these is great as far as material feel and fit on the body, but the separate pouch design is awkward and ill-fitting.  The lower pouch "cups " you well and holds you in place, but the upper pouch has a material flap fold that causes you to flop out of the upper pouch into the lower pouch over time--so there is no continued separation throughout the day of wear.  I have other brands of this separate-pouch design that work very well and separate the body parts into different pouches. The design of these underwear does not work well.  Maybe if you are a healthy "show-er" body type it would work by filling more of the top pouch in your normal state but if you are "grow-er" type there is an extra amount of fabric and a fabric fold that keeps you from staying in the upper pouch....after a while of wear, I find everything to be stuffed into the lower pouch and I am adjusting myself for comfort.  Poorly designed pouch area makes these boxer briefs a non-starter.
