I'm wondering if i can create a hammock knee-pillow from a dry bag by simply "inflating" it. I'm not sure which, if any, brands are air-tight. I need your help to test this.
If you have a 20L+ dry bag (the kind with a roll-top and clip), please try the following and report your findings:
1) As best as you can, puff the bag up with your breath, roll the top down extra securely and clip shut.
2) Use the closed bag as a knee pillow or just let it sit out a few days by itself.
3) Observe if the bag deflates or holds air over night.
4) Report here if it "WORKED" or "FAILED", and list what brand/model bag you have.
I am interested in your findings. Thanks for the help!
