Arc'teryx Cerium SV vs Outdoor Research Ferrosi Hoodie - Women's

Due to the nature of down, breathability should be less important than holding in warmth. High exertion should be for synthetics.

So as you're moving and you're building up heat, this material is going to breathe a little bit better. It's a ripstop nylon with spandex in it as wel...

In terms of fit, the new model for 2017, in a small, fits incredibly well. I am 5'11 and 150 lbs and the jacket fits well to my body, with no loose or too snug areas. The new waist band synches are incredibly useful in maintaining a good torso fit when extending your arms above your shoulders. The fitted elbow collars are great for rolling up your jacket's arms to the elbow, and synch around baselayers well

My only complaint is that the XS is pretty big on my 5'1, 98 lb frame (it looks like I'm wearing somebody else's jacket). I kept the jacket anyway because it's useful and fills a necessary hole in my jacket lineup--perfect for the windy days we get in Colorado.
