Righto for pack pockets. Great idea, oh Meshmeister. Although really sopped stuff might dry out faster in a mesh pocket. One year, I tried packing the tent in a stuff bag made of fiberglass screening and strapped to the outside of the pack. Surprisingly, a wet tent dried out a lot while hiking.
About fiberglass screening. Even some of the MYOG materials sites sell it.
But would need to test it some to find out how wear resistant it is, if at all, and if some types are more durable than others.
For other mesh applications where ventilation is needed, like a mesh backpanel, or the seat and back support for a camp chair, all those little holes in the mesh are needed, I think. I found I could use my camp chair much more comfortably during or after rain when the cloth seat and back were removed and replaced by Leno mesh that was not very water absorbent.
Being a big fan of suspended mesh backpanels, I appreciate that all the little holes are needed to provide the ventilation that keeps the back dry.
Not too much added weight to use the 'Rawhide' for a portion of backpanel.
But for a chair, it is substantial. And the Leno mesh caves and distorts after a while. To keep the weight down, the 'Rawhide' chair seat will be smaller, and the chairback will be both smaller and the lighter Leno.
Wonder if the fiberglass screening could be used for a backpanel. Will have to ponder that one.
