Nasty Pig is Here!UnderBriefs is happy to add Nasty Pig to its catalog. Nasty Pig, founded in 1994 and based in New York City, designs innovative clothing and edgy products for the masculine, sexually self-assured man. We've been a fan of their underwear products for a number of years and know that many of our customers are fond of Nasty Pig jockstraps. And now, you can buy the Nasty Pig Core Color Brief or the Nasty Pig Core Color Trunk; both are available in red or blue for $18. Or you can get the Nasty Pig Sport Jock for $22.
