I bought this jacket for PNW winters and I can’t think of anything I’d do to improve it, outside of maybe a right wrist pocket. I haven’t taken it snowboarding since I have a dedicated jacket for that, but I could see it being a little warm unless you were in the teens F.. This jacket with a base layer would probably be good below zero for a long time under no exertion. Fit and build quality are what you’d expect of Patagonia.

I’ll report back once the temp drops, but this jacket seems to have it all!

It's been years since I've had an insulated ski jacket. I'd been running a separate shell and fleece/insulating layer while skiing, but seeing as I'm a strictly an inbounds-skiing Dad with the commensurate body and declining "cool" factor, I decided to get myself an all-in-one this time around. The Primo Puff was a riproaring deal - more than half off MSRP in early spring. I picked a blue one up even though I knew I wouldn't be able to put it to the test until the 2020-2021 ski season (COVID closures). Around town, it's mostly great. Fits true to size (L for me, 6'0 200 lbs) The hood is sized for a helmet and very floppy if not cinched up. The hood cinches are also pretty finicky, and I'm not sure how they'll hold in the long run. I'm confident in Patagonia's warranty if the cinches lose their grip. The zippers are a little on the "sticky" side but nothing like the Millet rain jacket I have, thankfully.

Not mentioned in description, it has an insulated collar to keep wind and snow out when hood is down. Also has insulated cuffs for same purpose. I use for snowboarding and to wear to work when in Canada (bought grey color). Excellent fitting over helmet. Love all features of it. Light weight and easily compacts into carry on suitcase.
