I'm no DIY expert - in fact, I don't even own a thread injector.

BUT looking at multipurpose/similiar items, couldn't one design/make a pack cover/gear hammock that would include the necessary items so it can also be used as the infamous Jerry Chair?

One could use it for a pack cover, Jerry Chair at camp, and a Gear Hammock. To be totally waterproof, one would have to seal any required sewing.

Am I thinking too far outside of the box? Thoughts? Ideas?
