unsure of weights, but you could use the ultra cheep rain pant and jacket I have seen in Walmart and other discount stores which is basically plastic, or use a construction sized trash bag cut and then taped together to use as a sleeping bag inner liner. Again, I’m not seein the advantage, I pay extra for breathable stuff as I hate to be sticky, stinky, sweaty if I don’t have to be.
As as a construction material for make your own garments consider the polycro window liner stuff on amazon. An inexpensive alt to silnylon for initial diy project. Can seam seal with tape or a small iron that can be found in craft stores. Or cut up large trash bag or plastic sheeting for initial trials until happy with patterns. (I do this with heavy duty plastic sheeting) you can sew on machine with fine needle and thread and long stitch width on plastic. It doesn’t hold well, but again I use for prototype before the fanicy material investment.
DIY can be fun; HYOH!
