I am 1,75 m small / large and have the jacket ordered in size 6. It fits ziehmlich well, only in the leg-hip can not go on without the jacket movement limited to be. But if I leave open the last Knop's all perfect.
From this standpoint, the jacket krigt still 5 out of 5 points from me!
Yours sincerely
A very satisfied Army shop / Amazon customer
