These APOLLO Mesh Briefs are definitely not for guys with something to hide. They are made from a soft and flexible nylon mesh that is fully see-through. The convex front pouch is double-layered, which helps keep some things left to the imagination. However, when stretched out, it still becomes see-through and reveals everything. Some mesh material can get scratchy and uncomfortable, but that is absolutely not the case with this pair. We tested over a dozen different materials to find the perfect fabric blend that is sexy and see-though, yet still ridiculously comfortable.  Materials: 82% Nylon, 18% Spandex
