After careful consideration and months of research i finally pulled the trigger on this jacket...best gear decision yet!!! 4 days in Breck, jacket kept me warm & dry, was flexible and practical. i am 5"10 170 and the Large is great, Medium was too tight in the arm pits

I bought this jacket after investigating all of its features. This jacket is very weatherproof. I do not use it for skiing or mountain climbing. I use it for everyday use in Chicago. The one thing I did notice is that I was expecting it to be very very warm after all the reviews. Well last week it was 10 degrees in Chicago and I was wearing the jacket in the yard while I had the dog out. It was a bit cold, I was confused since I heard how warm this jacket is. I spoke with several people and was told this jacket is made specifically for "technical" use.. ie lots of activity.. So when constantly moving, it does stay very warm. If standing still, you might feel a bit of the chill at lower temps. To solve this issue, I bought The patagonia R3 fleece (breathable fleece). When I put that on as an underlayer to the Primo Down Jacket, everything was awesome and toasty again. So if your not working up a sweat and moving alot, just throw an underlayer on and all is good. This jacket is great. When I am moving around and being active, I definately do not need an underlayer. Great jacket and very stylish.

I am sure you have all seen this jacket highlighted in just about every outdoor and ski magazine this season as this is Patagonia's flagship jacket. Well I am here to tell you that it does not disappoint! Think Down Sweater sewn into the Powder Bowl Jacket and you are on the right track. If you want a jacket that will keep you toasty warm in the most frigid days on-hill, while still looking totally stylish and having the highest quality waterproofness and breathability, look no further friends....this is it! This jacket has changed the way I think about layering and insulation. Just put it on with a thin baselayer and COLD BE DAMNED!

Love this Jacket...Extremely warm but vents very well for when it warms up in the afternoon. The nylon outer shell is super tough.. had a close call with some pine trees and thought I ripped it for sure but not even a mark.The one down side is the hood does not fit over my Smith Holt helmet but its not that big of a deal.The Audio pocket is well thought out as well ..There is a small zip up pocket inside the left chest pocket which has a headphone access hole so you can have your tunes within easy reach... I'm about 5'8 165lbs I went with a Medium Fits perfectly no need to size up for layering with this jacket as it is all you need other than a base layer.
