This is considered to be the one of the best Arcteryx jackets for those who are fans of the dead birds.
It’s comfortable in 40degree weather with activity. Toasty at 50. Known to shed heat well. It is the replacement to the venerated Atom LT. Much better per reviews in outdoor gear labs and etc
At time of deal posting 10 mediums in stock in black
Hope this helps someone. I would jump on this if I hadn’t already purchased a month ago
