Revision is not always good

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.

Hello Trevor, thank you for taking the time to share your feedback. We're sorry to hear that the fit of the current Thorium Jacket did not meet your expectations. We understand that guests familiar with previous generations of the Thorium may notice significant differences in fit and silhouette. The latest Thorium was intentionally updated with a boxier fit to improve layering capability and warmth, along with increased down fill and larger baffles for enhanced insulation. While these changes were made with cold-weather climbing use in mind, we recognize that they may not align with the fit preferences of guests who preferred the slimmer profile of earlier versions. We appreciate you taking the time to share your detailed comparison, and we'll be sure to pass your comments regarding the fit and proportions along to our team.

Fit change, not the same thorium.

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.
