Thanks for sharing, Justin. I love the fabric on my nano air, so I’d also be excited about a hooded windshirt version. The fabric has a nice feel to it and excellent stretch. Its not durable enough for heavy bushwacking, but for most backpacking scenarios on and off trail it would do just fine. The DWR treatment is also quite good at least when newish.
Another suggestion thats out now and can be found for quite cheap is the nike impossibly light jacket (not shield version). My L is like 3.4 oz (I think) and material is softshell level breathability. I had my eye out for years, and couldn’t find anything like it, until the Nike.
