The Aeros Ultralight Traveller Pillow packs down as small as the two packets of peanuts the airline provides as your in-flight meal - and it will keep you happier far longer. A supportive TPU air bladder with oversized 'arms' for support and a narrower neck area permits a snug fit between your neck and the headrest, and the 20D polyester fabric is soft against your face. For additional support secure the two arms together with the adjustable neck closure.
