Like Imagedude I've got a mountaineering background and have been using the belay jacket concept for years now. It has pretty much replaced the layering system for me due to it's simplicity. When you're active, even in cold weather, all you need is a base layer or thin insulating layer under your wind or waterproof. Then, when you stop, you just put your belay jacket on top of everything to stay warm while you're resting.
I've been using a Montane Bivvy jacket for years (I can't seem to kill it), and a Patagonia DAS parka.
Cheers, Michael.
But as I understand it, synthetic fill won't warm very much when whet, am I right? And if the outer is waterproof, won't down be just as effective?
To clarify the abouve I saw a new rab in a shop a few weeks ago which seemed to be thicker then mine which may be more suitable. I think rab stuff is great.
