If you had to size up on the Rock coat to accommodate your shoulders (narrow on the Rock), you won't need to do that on te Board.
This is me in the sz 6 (my normal Schneider outerwear size) and it's def not as snug in the shoulders as the Rock. Body is plenty roomy in Schneider's typical boxy cut
One of the most slept on coats this season IMO. Fabric is really fantastic and coat is super versatile.
Here you go.
