I have a rather large underwear collection ( at least according to my wife ) So I am always happy to try new ones out. I am 5'8", 160 lbs, and wear 34-inch waist pants. Size Large fits me well. I have another pair from this company in a size XL. It is too big, even though the chart shows it. My other pair just went into the trash. I have this pair on right now. It fits well and doesn't creep up my backside. The pouch holds my junk pretty well also. Being low cut, the waistband does not roll down like some of my others do.I think I will be using these to sunbathe next time I lay out to get some sun. If my neighbors are watching they will probably be glad that I at least have these on. LOLI like these and am happy to have them.
