Yes, I have my eye on a BD Oneshot or BD Lighthouse, both made of Epic material. (I'll have to wait for my number to come in though)

I tested my home sewn Epic bivy week before last. It's not seam sealed yet so I was under a tarp. After two nights, temps about 35F, with the last night in the rain, I packed my sleeping bag and bivy in a dry sack. I weighed them when I got home. Absolutely no moisture was retained, so I know Epic breaths - at least under these conditions.
