That jacket has got to be heavy as hell ;)
In response to the Epic question, it's supposed to be "more water resistant" than a DWR fabric, but not waterproof. In my experience, momentum/intrepid accomplishes this as well or better than epic due to the insanely tight weave. Water beads right off of it, but it's definitely just DWR fabric.
Like Eric mentioned though, the less waterproof/resistant the fabric, generally, the better it breathes, and thus, the faster it dries. My first gen EB Downlight sweater appears to actually suck water into the fabric, let alone "resist" it. I'm pretty sure there's no DWR coating at all, it soaks out fast in rain, but likewise, it dries faster than any other down item I've ever had/used/made, etc.
My 2c, Epic is not worth the weight or cash investment, but that's just my opinion, and I'm sure others will disagree with me.
Like I said, if you're hell bent on a "waterproof" eVent jacket, I can make you one for about what you'd pay for a FF one, and I can seamgrip or tape the outside seams. The issue is, and I suspect the reason why you wont find any jackets like this, it might end up pretty ugly in the end. Very functional, but not pretty.
The fabric is waterproof, but the seams will wick moisture. Un-taped, like the FF jackets, the shell will be very water resistant, but not waterproof in the "rain" sense at all.
