This design is a great improvement over just an inflated rounded rectangle. I made a "pillowcase/stuff sack" from two Tyvek mailing envelopes, adding an elastic cord drawstring on one end and two folded tabs, one on the center of a long side and the other on the opposite end. Right-side out, I have a stuff sack that holds my sleeping items. Inside out, I can us the tabs and another piece of elastic or shock cord to secure the pillow either around my pad or to the ridgeline inside my hammock. The "inside" is my clean side against my face. This sack might be large enough to hold the pillow, night items, (Klymit) air mattress, and maybe a light down blanket. Washing the Tyvek multiple times helps it to soften and get quieter.
