The Aeros Premium Traveller Pillow by Sea to Summit offers the jet-setting traveler an exceptionally comfortable neck pillow with low weight and pack volume. Based on the same manufacturing process that Sea to Summit uses for its other premium pillows, a particularly durable TPU bladder has been developed to provide ergonomic support for sleeping while sitting. The voluminous side areas of the pillow stabilize and support the neck when pressed against the pillow. The soft 50D polyester cover ensures a pleasant feel against the skin and exceptional user comfort.
