The Aeros Ultralight pillow has been refined from three ideas: light, compact, and comfortable. The result is a 20 denier pillow with shapely support that can be packed away into a neat, small stuff sack. From the airplane to the mountains the Aeros Ultralight is the perfect travel companion for those on the move. It is made from 20D laminated polyester with durable RF-welded construction and laminated with abrasion resistant, high strength TPU. Scalloped bottom edge centers pillow around your shoulders whether you are sleeping on your back, side or upright in a chair. The multi-functional valve allows for easy inflation and deflation.
