Take a thin, snug hoodie. When your ready to sleep, take your arms out of the sleeves, zip it up, and cross your arms across your body. You’ll sleep better and your back and shoulders won’t feel as strained. I also have a long, wide scarf that i use for this. For neck pillows, i like the turtl one -hard but kind of flexible plastic with a wrap around sleeve. it works well and it’s easy to pack.
