A tie has been invented in Japan that can also be used as an inflatable pillow.
The 'Nemuri Tie' can be inflated into a handy head-rest by someone blowing into a hidden air vent, which is positioned on the reverse of the garment.
The inflatable part of the 'Sleep Tie', its translation into English, can be easily removed to appear like any other.
According to the Asahi newspaper it will cost around £20 and is reportedly made out of silk and micro fibres to keep people cool in the summer.
