The PrimeMan Brief provides engineered freedom of movement for guys who are active and lead a dynamic lifestyle. A deep seat and wide leg openings make it perfect for guys with larger or more muscular legs, and is designed to work with the natural movement of your body. The anatomical pouch keeps things supported, together, unmashed and adjustments unneeded. The Micro Modal/Lycra blend is so soft, so anti-bacterial and moisture wicking, it's life-changing. Your legs are free to move freely and breathe freely, just as nature intended. And the silky waistband stays in place without constriction.
