Q: Is the sizing in Inches or is it European sizing. (If I wear a size 40 inch coat, do I order a size 40 in this?)
A: The sizes relate to the chest size in inches.
Q: Hello, is this fully lined , does it have any internal pockets and does it have cotton venting under the arms?
A: There appears to be one inside pocket on the left which is approximately 6" x 6" and 2 smaller ones, one each side approximately 3.5" x 3.5". There are underarm patches and it is fully lined, but as there is no label to identify, so can't be absolutely sure they are cotton. Most of them do have the anchor buttons, but the odd one does appear to have 3 crowns on the buttons.
Q: Does this jacket have the two large pockets on the back?
A: Yes it has 2 pockets at the back near the bottom. They measure approximately 18cm wide by 24cm high.
