You can wear silica gel since about 1918 - only needs some heat to get the water out and cold to condense it.

Then again, why would you want to wear your dehumidifier (ok ok water harvester)? Is it for excursions into damp areas, so that you can then return to your dry home to extract water?

Then, I believe everything in this video still applies.
