Creases
The sleeves crease up more than I'd expect. This is in part because of the storm cuff. The sleeve essentially has a hard stop at the shoulder and another at the wrist and so any excess creases up along the length of the sleeve.
There isn't enough ease across the shoulders but I'm starting to think that fully lining in melton isn't going to work. I love how substantial it makes the coat feel but in reality, it feels like armour. The melton is 650gsm, the roll is 155cm wide which makes it just over 1kg per liner metre and it takes 3.5 metres to create the outer and line it.
That makes for a 3.5kg coat.
