jordan emerywrote a review of Marmot Astrum Jacket - Men's on February 27, 2017
Familiarity: I've put it through the wringer
Fit: Runs large
I love this jacket, it quickly became my go to. I wear it all the time and everywhere in temps from 50 down to 15 degrees or lower (with a small fleece underneath in that cold). Somehow it manages to keep me warm, but not too warm. And yet, it still seems to provide plenty of warmth even when it is windy even though its breathable. It has held up very well so far, after 4 months even the DWR finish is still going strong deflecting light rain and snow effortlessly. I highly recommend this jacket.
One last note, I normally wear a medium and definitely had to get the small in this jacket. The medium fit me like a large normally does.
