Pouch fit is a minor miracle.
OK this is a different experience than most briefs. The pouch is shaped so that everything stays in place and doesn't get mashed up or pushed forward in an obvious way. It almost seems like a custom fit. It's one of the few briefs I've worn that doesn't require constant tugging and adjustment. Meat and potatoes all stay aimed downward where I put them, and there is no ring or shelf inside to cause chafing. If something comes up and the pouch needs to expand temporarily, the stretchy mesh material lets that happen as necessary, but stays in control as the shape adjusts, and doesn't gap.
As far as the butt lifting capabilities, the wide elastic straps are promising, but the XL is true to size and maybe a little too loose to really lift my smaller tail. I'm going to try to shrink the elastic just a touch, and maybe buy the L to see if it's a little bit more snug in the back.
All in all I'm really liking the way these briefs fit and feel.
