I'm one of those who, once in awhile, end up wearing everything.

I have a Granite Gear stuff bag for my spare clothes. It's very light, but it's also very tight cloth (almost air tight). Yet the cloth is comfortable on my face. I usually use that for my pillow with the clothes.

When I'm wearing them all, I've used two different methods: I've simply blown up the bag and tied a knot in it (makes bag too small, and air did not last whole night--had to do it again when I got up to water the bushes), or, more successfully, just stuffed it with duff. Worked fine. Best, jcp
