SUL Wind and Waterproof top

What counts as SUL in your opinion? The very lightest silnylon jackets are under 7oz (Equinox Gazalle) and so too are the lighest "waterproof/breathable" jackets such as the Marmot Mica, old TNF Diad and Patagonia Specter.

The lighest I know of is TNF Truimph Anorak at sub 6 ounces.

Some people go lighter and use thinly coated windshells (Patagonia Houdini or Golite's stuff) when they only expect brief showers or just snow.

Also, MLD makes a Cuben poncho that is about 4oz.

Any waterproof garment will also be (essentially) windproof…

there is also driducks / dropstopper / rainshield o2 all of which are made from propore or similar material. Depending on your size these run from 4.5-6.5oz, are waterproof, more breathable than most materials (all the materials in this weight range), and fairly windproof. They are sligtly air permeable which I think is a good thing. Only downside is that they are slightly fragile. The counter to that is that they are easily repaired with duct tape and cost around $18 for jacket and pants.

If the criteria are wind and waterproof and SUL — then another vote for Driducks. Bonus: they are very breathable too.

As for the fragility of the material… not a problem unless you are bouldering or truly bushwhacking.
