I bought a customer fleece jacket a few years ago that was very large in the body for an XL, with very long sleeves. Bought one of these jackets the other day and it is smaller, in my opinion, with more moderate sleeves. I used to size down in their knit jackets, after that experience and the size L fit but was a little snug. But with this jacket: It fits, but it isn't too big, the way the other jacket was. Blair has changed its sizing, so you really do need to take your measurements and then select size based on the chart for best results.
