The innovation among the luxury hotel pillows: The outer chamber is filled with a patented blend of small white duck feathers, white duck down and high tech down alternative fiber, the inner chamber filled with 100% white duck feather. The ideal mixture of 100% natural feathers and down and a high-tech 3D synthetic fibre provides a particularly lush "loft" and, in combination with the 3-chamber construction, the perfect support feeling and simultaneous softness typical of luxury hotels.
