Have an EE 20deg Rev-X that I really like! Last fall in CO was a friggin' soaker & I got by OK with the down Rev-X quilt, but the footbed area did soak in some moisture from contact with condensation inside my Tarptent. The moisture soaking wasn't enough to lose warmth, but the down in the footbed area did get a bit 'clumpy' and needed aired out in the morning. If I was able to keep the side flaps open, the condensation would likely not have been a factor. Just that it poured every dang afternoon and night!
Anyhoo, that little bit of moisture soak-age was enough excuse to order a synthetic 20deg Prodigy. Waiting patiently for it...
