Jack Adams introduces the sexy Modal Eros Bikini Brief made with a luxurious Lenzing modal fabric from Europe and designed with an opening in back to reduce booty sweat. Like all Jack Adams underwear, the Modal Eros Bikini Brief features a natural pouch which has a special, contoured shape that conforms perfectly to the male anatomy. When you pull on a natural contoured pouch bikini brief, your genitals hang gently and naturally in the pouch, providing a feeling so comfortable that you'll swear that you're not wearing anything at all. The back of the pouch softly hugs the area behind your scrotum with just enough tension to lift your genitals up & forward, preventing your boys from falling between your legs for all day comfort.
