Familiarity: I've put it through the wringer
Fit: True to size
I picked this jacket up as a "why not?" during BC's 30% off sale a few weeks ago. When I first pulled it out of the goat box, I was some what disappointed. It's VERY thin and lightweight, how could something like this keep me warm? Well, I was pleasantly surprised when I put it on. Holy warmth! In 40 degree weather with just a T-shirt under it, I was burning up. Lately, here in Colorado, we've been having 15-20F degree highs with some light snow. A good base underneath and maybe a light shell over the top is all you need for a snowy mid day hike. I went with a small and it fits me rather snug. I can get a skin tight base and a light fleece underneath it, but just barely. However, I didn't intend on buying it solely for layering purposes, so fit is great! I also own the down sweater jacket from Patagonia, and I can say that this one fits me far better and is much more practical in a backpacking/skiing setting. Speaking of fit, the cut of the jacket is very flattering for athletic builds while still allowing for excellent range of motion. I honestly love this jacket so much I don't think I've taken it off for the past 2 weeks... (Have I really not taken this jacket off??) Don't judge me. Its like walking around wearing a sleeping bag, you'd do it too.
Bottom line: Awesome down puffy warmth and weight at softshell thickness. Primaloft for the win! You can wear it from the slopes to the breweries and still look you belong on a Canadian glacier.
