The Aeros Ultralight Pillow is a perfect mix of weight, size, and comfort. The result is a comfortable 20 Denier pillow that can be packed into a tiny and convenient pouch. Whether on a plane or in the mountains, the Ultralight Pillow is the perfect travel companion for on-the-go. Curved internal chambers create contours that perfectly adapt to the head. The cutout at the bottom allows the head to rest centrally on the pillow, whether you are a side or back sleeper.
