My brother has one of those little tiny backpacking pillows. The last time we were on a trip, he couldn’t find it after everything was set up.
So, he made do the way people used to, by wadding up some clothes and other gear and using that for a pillow.
Not ideal, as you know if you’ve ever tried it.
The next morning, I found the pillow.
It was obscured by the dark, but was lying at the door of the tent, partly covered by the little flap of nylon that covers the zipper of the tent.
Yeah, it’s THAT small when packed away.
