I'm at about 30 days this season and have now used the jacket in all conditions. I'm very happy with the performance from a waterproof perspective. I've skied down to the village through rain several times and the inside remains dry while the outer fabric has not become saturated (although it does not fully bead off in a real downpour, after a few minutes out of the rain the outer is fully dry). Breathability is impressive, I've kept it on while skinning in moderate temps and the inner fabric does not saturate (although my base layer was slightly damp, just means the jacket should have come off).
Durability is great, done a decent amount of bushwacking with no visible damage to the outer fabric.
Only complaint is the bottom of the front zipper sometimes ices up on big powder days, making it hard to fully unzip.
