Roger thanks. Same as the DAS. The (now) ancient ID Dolomitti is about the only synthetic puffy I've owned with enough loft to be a primary belay jacket in truly cold conditions. There are a few others that push toward 150-180 g/m2 these days, but most burn weight on heavier face fabric than I care for. Down gets hard to argue against as the mercury dips below slush conditions anyway.
Snowy,
My favorite belay jacket is the Mountain Equipment Citadel. Lofts almost like a down jacket. It's basically waterproof, also. It is rather heavy. That's the only downside. It truly kicks the [bleep] out of my DAS for warmth and weather proofing.
