Jennifer Y.wrote a review of Arc'teryx Sentinel Jacket - Women's on January 13, 2014
Familiarity: I've used it once or twice and have initial impressions
Fit: Runs large
I was very pleased when I wore this through this weekend's wet Cascades snowstorm and found that I was still dry under my jacket. I do wish it had wrist gaiters, but otherwise am glad that I'll be able to take this light and waterproof jacket to the backcountry.
Fit: The hip area and powder skirt are pretty snug, and I have small hips. But the waist/stomach area is huge and baggy. I am typically between a M and L and sized up to a L. It's pretty big, but with layers on it's just the right size. The arms/shoulders are roomy and don't restrict movement.
