In that situation, I probably would have gone with something like the following:
1. The top. Mesh long sleeve top. A breathable, quick drying, wicking, lightweight, low odor baselayer short sleeve top over the long sleeve mesh baselayer (many things here could work, like OR Echo), and then a Terramar polypropylene long sleeve baselayer over that (unlike other PP baselayers, this one doesn’t wick, but sheds, and doesn’t hold much water).
Over that, I would wear a poncho with a WPB front insert (from top of chest to near groin).
2. For bottoms, I would wear mesh baselayer with nylon shorts with EPIC fabric connected to them for the pant legs.
3 Feet: Could go one of two ways. Thin alpaca-synthetic blend socks with WPB socks over same, and thin PP socks over that with trail runner type shoes.
Or, thin alpaca-synthetic blend socks, with thin PP socks over, and thicker PP socks over that, and a thin, lightweight, tightly woven/wind and water resistant DWR treated polyester fabric over sock over these, and with slightly over sized hiking sandals. Why, everything in this system dries super fast, even though your feet will get wet. You can wring and/or swing out the water in the PP socks. Not much material in the hiking sandal to dry to begin with. That’s the main idea, to get everything dry as fast as possible, while still having breathability.
I don’t find encasing my feet in completely non breathable material to be a tenable solution tbh. Might be ok in very, very cold and very dry conditions (vapor barrier and preventing moisture ingress into thermal layers), but not humid and very wet conditions.
(I would have a backup, dry pair of the thin alpaca-synthetic socks, because these don’t dry as quick as the other layers).
