OK, got the jacket on the scale. It's a touch heavier than advertised at 10.5 ounces vs 9.9, size M. I've only had the chance to wear it around town, but it seems to work well with some of my bulkier baselayers (like a midweight Smartwool zip T). Very comfortable, it flexes very easily.

Not surprisingly, it feels a little cooler than the pants. I expected that, my torso (and probably most people's) is more sensitive to temperature than my legs. Can't wait to try it out in cooler weather to see what it's limits are.
