I have tried every type and style of underwear I could possibly get my hands on over my last 38 years to stop the testicular pain and groin discomfort. Eventually I just gave up and went commando thinking that would solve the problem. Unfortunately, the constant adjustments continued and the sticky sac to leg experience continued. These underwear eliminate all of that...I don't wear them like you're suppose to, I pull everything through the hole instead of using the two 'pouches' but it's seriously like I'm not wearing anything at all! No discomfort, I don't even think about it anymore and don't realize it until the end of the day. I have literally been telling everyone I know about them...it's the way underwear should have been all along...how did it take so long for humanity to figure this out??!?!?
