I have an inflatable bean shaped pillow from way back, probably from REI. I underinflate it and it’s quite comfortable. I put into a DIY fleece pillow case which works for me. Deflated pillow, cover, fleece cap, socks, ear plugs and whistle all slide into a nylon stuff sack (half the size of a box of cereal) and pack with the rest of my nylon motel. Standard kit.
