This is my second monkey fur fleece and they have made improvements with the fabric and the fit! I'm 5'6'" and thin and the small fits me perfectly. I had to get a medium on my old one for the sleeves to be long enough but on this one they are even longer than my old medium! This fleece is SO soft, snuggly, cozy, and warm! It is not wind proof but under any shell it is an unbeatable winter jacket that I used for many brutal winters in the mountains. I waited years to buy my first one and wished I had gotten it sooner, definitely worth the money!
