5XL is perfect for an average 6 foot Australian. And it’s pretty warm too, without being over the top. Good looking and well made, although the patches are a bit naff and will be replaced, but loving the jacket!
Jacket is as described. I'm 180cm and XXL is hardly big enough. Quality looks very fine. I didn't ecpect winter type warmnes because of other customers reviews. If I order another I will take bigger one.
