Kuiu Yukon jacket fit?

[Dirtywater]

For context I am 5’10 165lbs typically medium jackets are plenty big on me. I read the Yukon had plenty of room which was good to hear because I plan to always have a few layers underneath.
Got a size medium today and it fits fine everywhere but the forearms..they seem super tight. Just wearing a t shirt if I bend my elbows I feel constricted. Is this normal? Does it break in or something? I can’t imagine wearing any layers as is.

But like I said length and chest are fine it’s just elbows down that seems extremely tight
