Nice and burly.
This jacket is burly. The jacket should withstand some foul weather. The jacket has a nice fleece lining for some warmth. This shell has short sleeves compared to arc'teryx, rab and so forth. Consequently, When I lifted my arms as if swinging an ice tool, the jacket left two inches of my arm exposed from where short gloves stopped. But for activities where you aren't raising your arm all the time above your head, it should be great.
The helmet compatible hood is large. Seems on par to Arc'teryx size. My Smith Variant brim helmet fits with no problems as well as the petzl elios.
I havent worn it enough to comment on breathability.
