Jojowrote a review of Arc'teryx Atom LT Hooded Insulated Jacket - Women's on December 27, 2013
Familiarity: I've put it through the wringer
Fit: True to size
I use this jacket for everything- hiking, backpacking, climbing, day to day use. It is super light, warm for its weight, extremely comfortable. I would say it is true to size- I am 5'2", ~115 lbs, chest ~ 35", and I normally have trouble getting sleeves to fit properly as I have wider forearms from climbing, but the XS fits me perfectly. I can wear two long sleeved shirts under it. At first I was a little worried about the sleeve cuffs being too tight, but they loosened to a comfortable fit with use. I always wear it with a thin fleece baselayer with thumb holes, and that layer fits me fine under the cuff. Would definitely recommend to anyone. I've used it a lot for a year and the jacket is still in great shape. Got the poppy color and absolutely love it.
