jainsvwrote a review of Arc'teryx Thorium AR Down Jacket - Men's on November 24, 2015
Familiarity: I've used it several times
Fit: True to size
I decided to go with the Arc'teryx Thorium AR after much research to try and stay warm in upstate NY.
Fitting: It fits to size. I am generally an XL with most companies, and Arc'teryx does tend to have an atheletic fit. That said, the jacket fits snugly without limiting my movement. I could likely fit a small/thin fleece under and/or layer over it with an overcoat if needed.
Warmth: So far haven't put it through the ringer mid-winter, but it has kept me warm with just a T-shirt underlayer in 20ish degree weather.
Style: As always, Arc'teryx products look good.
I would definitely recommend this jacket.
