Boys Long Johns Gap Collection
Also known as long underwear or thermal underwear, long johns supposedly date as far back as the 17th century and became popular as sleepwear in the 18th century. No one is certain where the name comes from, but the alleged creater of longjohns is John Smedley. Longjohns were initially designed to trap body heat and insulate the wearer against cold air. European manufacturers traditionally used wool or wool-blends, while American long johns are usually made from cotton or a cotton-polyester blend. Initially used as loungewear, when long johns became popular as sleepwear they also become popular sleepwear with children. The long johns for boys at Gap continue this tradition of warm sleepwear and loungewear for children.
