That's right. When I bought it the raw measurements were perfect for me and I decided to not do an initial rinse. Over time I tried to not get sweaty in the jacket so as not to need a wash. Last month I saw the new batch come out and thought I might as well wash it and if it shrinks too much I have the option to get one at the proper size. After a good cold water soak and wash, and hang dry , it only lost about a half inch on the sleeves and negligible amount in the chest and shoulders. The elbow creases are so set they didn't move at all. Despite not really being forced to get a new one due to shrinkage I bought one of the new ones in a size up. because why not?
The guys at Mister Freedom sent me an email stating it was the last in my size but it was the rinsed one they used to make the size chart. I took it and this go round I don't need to worry about regular washes.
