My Cabela's rainy River Paclite parka, in size Large, Tall, weighs 15.8 oz. by my digital scale. I'd say for a Small, Regular you'd save several ounces.
Yeah, it's not strictly UL, but it's still very light and compactable for a breathable and durable (as opposed to, say, a Marmot Precip) parka.
AND it's cheap for a Gore-Tex PacLite parka. No pit zips but the mesh-backed large slash chest pockets work fine for me when zipped open B/C they have wide zipper flaps to keep out rain.
