This is a thin neck pillow that supports the neck with the shoulders, similar to the Trtl pillow. I bought it for long flights because I can't sleep unless my head is stable, but I only tried it on once before a trip and didn't use it. (Washed) The fleece material on the surface can be removed and washed. #neckpillow #travel #airplane #sleep #necksupport #neck #outdoor #pillow #airplane #shinkansen #nightbus
