In reply to davidhw:
I've got a paramo torres. I'm actually wearing it right now because my heating has broken down....
Anyway, its nice. I can't really compare the warmth because its my first belay jacket but what I can say is:
Its pretty damn warm.
Its cut very large in the body.
Has a good hood.
Has a fairly tough outer.
Neck is a little tight when zip is done right up.
The hand warmer pocket is nice, as are the mesh inner pockets, great for warming up rock-boots or gloves.
The zip is long enough not to worry too much about getting it on and off (even with a helmet on).
Generally its well thought out and pretty sturdy feeling.
Best of all it resists water REALLY well, I was in a torrential downpour in the alps for 20 odd minutes, ten of those sitting on a chairlift with the water pooling on my lap, and inside the jacket stayed totally dry. After an hour sitting in the cafe it had pretty much totally dried out.
