Richard Doherwrote a review of Arc'teryx Atom LT Hooded Insulated Jacket - Men's on April 5, 2019
Fit: True to size
So far so good. I picked up the Atom LT a little bit leary, as I live in Northern Michigan and we have snow and cold weather about 4-6 months each year.
I need to layer a little under it, should be fine with a long sleeve shirt in spring/fall type weather, and I was perfectly warm with a hoodie underneath in below freezing temps.
Its a good looking jacket with a nice fit.
