I recently ordered some of the King Style Balls in One Ultra Pouch Briefs and Boxer Briefs from International Jock...

King Style New & Unusual at International Jock Underwear & Swimwear

They seem "OK" but definitely not like the original 2xist or Unico pouches.

Overall, slightly disappointing but may work for some folks. The waist sizes seem to run small so you may want to order up a size if you do give them a shot.
