This vintage Cuddl Duds white Long John was found recently in a sealed box in the back of a store room (new old stock), like a time capsule perfectly preserved and waiting for the lucky person for whom this will fit. This supremely soft layer will adapt to your body as if it had been custom made for your every move and comfort in mind.  Dupont CoolMax Alta works with Climatesmart technology to wick moisture away and trap heat, so it is constantly adjusting to you and your changing environment to create your very own personal comfort zone.  It remains neither too hot nor too cold, no matter if you are wearing it as a base layer in the office, sitting on a cold bleacher during a late-season football game, skiing or hiking in the Alps.  As with so many things, they don't make them quite like this anymore.  ASSEMBLED IN MEXICO OF USA COMPONENTS.
