I just saw there was more to your post. I spent three nights on line looking for laminated fabrics under many names. Actually, rain coat fabrics was the most successful "label."
There is one quilt shop which sells some laminates as part of promotion involving making your own sandwich wraps, food storage bags and lunch bags. I really didn't like any of the fabrics they stocked for the purpose of rainwear.
I made my daughter's -- more than 30 years ago -- from tightly woven cotton. I have a similar garment I purchased just before I made hers from a less tightly woven cotton. I also have a raincoat made from the sort of fabric I really want but finding such material is next to impossible.
The laminates generally come from Korea and the biggest source is from Korea and shipping takes about 3 weeks.
