Mack Weldon Silver Edition Underwear

In the supernatural world, silver kills werewolves and vampires. In the real world, it's favored by US Special Forces, Olympic athletes, NASA and now Mack Weldon for its super and natural qualities. It keeps you cool, dry and is naturally antimicrobial. Best of all — this goodness never washes out. Combined with super soft Pima cotton, Silver by Mack Weldon feels incredible all day long or 5 days straight, depending on your habits. You might not be slaying vampires, but you'll feel like a super hero, naturally.
