Obviously AnatoFree (Naked) Brief

The Naked Range is specifically engineered for those guys who are not afraid to go Naked.  The contour pouch, while it is slightly more roomy than other brands, provides comfortable support. The fabric for these underwear -- bamboo rayon -- feels as soft as cashmere but is lightweight and stretchy to provide additional comfort. Bamboo rayon is an eco-friendly fabric with antimicrobial properties, so it keeps your body clean and fresh-feeling. It's also resistant to fading and shrinking.
