The first really new idea in underwear for some time.  The pants are made with ultra-short legs and are a new style that gives maximum comfort, convenience and support.  Men need support every much as women need the support of a brassiere.  Doctors have recommended jockey shorts because of their masculine support which takes the strain off important muscles.  At the same time, bulges and shadows are eliminated so your outer garments hang better and look smarter.  The new Y front has a convenient angled opening so that it cannot gap, while the Lastex belt keeps the garment in place.  In the words of one American ad, it is “the underwear that ends squiriming for ever”.
