This is a great field jacket. Sizing is correct for this type of jacket. Having worn these coats for over twenty years in the military they are not suppose to fit like a second skin. With the liner in you should be able to move reasonably well without restriction. The only complaint I have is the velcro closure at the neck. It is not enough in order to close it on my neck. Easily fixed with velcro.
I would suggest this to anyone who likes field jackets as long as the quality and sizing stays the same. I may order another to have in my supplies.
