Warm and Cozy

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: XS

I bought this one in the buffalo check color. I find myself between sizes and this jacket/fleece was no exception so I ordered both the XS and S. Both sizes the arms were plenty long which I greatly appreciate, and both had ample room in the chest and waist area. I ended up keeping the XS because it overall looked nicer on me, but it's almost too high in the waist for my liking now and wish I would have went with the small. The small fit more like a jacket, so in the end it really depends how you want to use it. FYI the inside of the jacket is not fleece, it's smooth material which is good so it won't transfer fuzzies or stick to other layers.
