Jacquelynn N.wrote a review of Columbia Alpine Action Omni-Heat Hooded Jacket - Women's on January 9, 2017
Familiarity: I've used it several times
Fit: Runs small
Size: 2-4 top, 6-8 bottoms
Used in: 6F to 40F, walking with some pretty fierce wind and snowmobiling.
Findings: This kept out the snow, wind, and cold wonderfully, but I would have liked more pockets. Also, I'm not sure it would do well if it had been much colder, or if there had been more wind on the chillier days. On the plus side, I didn't overheat when I wore it near the 40s (with human-bowling wind).
Fit: I bought a small in Iris and a medium in Black to test the colors and the size, since I'm heavy-bottomed and others said it ran small. I honestly found the fit comparable--both were comfy, with enough room to wear underarmour and a thick sweater underneath, with some room to spare.
The main difference seemed to be in the circumference of neckpiece. If you don't like a snug neckpiece or have a thicker neck, small is not for you. Also, the optional hand warmer thingies were very warm, but felt a little short compared to the jacket's sleeve. When I wore it, it felt it felt like it was trying to pull my hand back in, even though the sleeves are almost too long for me.
Style: My clothing needs to be functional and look good, and this did both. It wasn't too sporty or bulky, so I felt like I could still rock the streets AND be comfortable. That said, I ended up keeping the black instead of the Iris, which was a little...middle-aged looking.
