I really like the pouch design for comfort - the other manufacturer that I know of who makes them is Jockey.  Thought I would try Munsingwear since it's a well know brand.  They're nice but the ones from Jocky are more durable and I prefer the way their pouch is designed over the way Munsingwear's are (the Munsingwear pouch droops/opens; the Jockey stays closed).
