Interestingly, there don't seem to be many about that are aimed at the hiking/climbing sort of market. Presumably the people most likely to buy this sort of stuff are skiiers and snowboarders, and that suggests to me that you'll have to pay over the odds.
Looks like Berghaus do something cheap (the RG insulated jacket) and Mountain Equipment do something heavy (the Pamir) and Crux do something bloody expensive (the Plasma). Rab used to do something that would have suited you (the Rogue) but the line seems to have been terminated and everywhere seems out of stock, now. Shame... seemed like a nice bit of kit when I looked at it last season.
There's also weirder stuff like the Montane Resolute, but that's probably too warm and insufficiently waterproof for you.
