From the same project that produced the Aeros Premium Deluxe Pillow comes this ultralight version of the Deluxe Pillow with identical dimensions. The Ultralight Deluxe Pillow was developed based on Sea to Summit's patented Air Sprung Cells technology. The use of this technology has allowed Sea to Summit to create a larger inflatable pillow made from just one layer, without the sensation of lying on a balloon. For just 130 grams more weight, you can now take an extra-large pillow on your adventures and maximize your sleeping comfort.
