Decent. I also went for a smaller size (M) that I generally read about for Under Armour underwear, but to tell you the truth, even in my regular size it fits just fine. I don't feel the elastic on my legs and waist. It is, of course, 5" so some people might be bothered that it won't cover the friction point of the thighs.

I have been wearing the same or similar ones for years. They have changed them a bit. They seemed slightly worse to me. They even changed the φαλλό-οπή for some strange reason.
