I ordered this in a Large, it was way too big (stroked by ego though) sent it back and what I love about Lucy & Yak is that you can get a different size with the refund process, very smart and helpful. (Otherwise I probably wouldn't have bothered).
I love it, have worn it most days since it arrived and already have another fleece from them, great material, quality feel, decent zips and all if all good value.
One slight improvement would be to have zip pockets (iPhone at hand)
