Virgin Atlantic is offering the unisex all-in-one sleepsuit "Onesie" exclusively to Upper Class passengers.

Designed by One Piece, it is designed for comfort while sleeping on board. The simple and chic black design features the words "sleepy head" on the back. The Onesie will be available as a trial to thousands of Upper Class passengers on overnight flights across Virgin Atlantic's long-haul network. It can also be taken home.

Model Amber Le Bon, daughter of Duran Duran's Simon Le Bon and model Yasmin, commented, "This sleepsuit is not only stylish, but also comfortable, making it perfect for long trips."

Virgin Atlantic was the first airline to offer sleep suits to upper class passengers in May 1994, allowing them to rest comfortably during 12-hour flights.
