I have a Thorium from back in 2022, and had to get rid of it as I outgrew it. The original was a Large and was such a great jacket. I have to say this new jacket has such an awkward fit. I originally ordered an XL to size up from previous model. The XL was huge but also in such a bad way, extremely boxy and shorter than it should be. So I got a size Large, which I was really surprised with. After trying it on, the Large fits better than the XL but is still so boxy and just too short. The jacket feels more like a streetwear piece from the 90's for style as opposed to the slim technical fit I am used to with Arcteryx. I have to look for something else as this fit is just so disappointing.
Fit has changed terribly, make sure you go in store and try it on. They're updated fit from a few years ago is changing the brand quite a bit it seems.
Amazingly warm and very durable. Fits very well. Great quality coat
