Jacqueline L.wrote a review of Arc'teryx Atom SL Hooded Jacket - Women's on November 20, 2019
Familiarity: I've used it once or twice and have initial impressions
Fit: True to size
I hemmed and hawed on purchasing this jacket for months. I liked that it was ultralight and came in high-vis yellow but when I saw it in person I couldn't quite reconcile the cost with the amount of jacket, especially when compared to the Atom LT which is frequently discounted while this hasn't been.
To say that I already love this jacket is an understatement - it is surprisingly warm. I think this will make an excellent replacement for fleece midlayers (which I hate) for fall/winter hiking and bike commutes when its windy.
The sleeves are cut a little long and shaped to contour the top of the hand so that only the fingers extend past the hem (instead of having a thumbhole, I assume). Overall I think the cut is true to size.
