Jockmail Supersoft Classic Briefs
You should have seen my face when I tried this one for the first time. I think I even said "Holy f*ck" out loud because it felt so good. The material is super soft, thin but not transparent, and very elastic. And the fit of these briefs is as good as its material: snug, so everything stays in place; and with a round cut at the legs, so your butt looks bubbly.
Material: Spandex, Modal
