I've done a bit of searching about open cell foam bottom insulation and haven't come up with too much. Has anyone made their own version of a SS? I'm thinking of ways to use open cell egg crate foam (or something similar) as bottom insulation for my DIY hammock. Yes, I know it's bulky, but it's also a lot lighter than my current carpet padding solution. I haven't found too much on anyone else using open cell other than the actual Super Shelters.
