This is the best warmer hoodie I've ever purchased.  Am so delighted with the quality and comfort of this hoodie that I've purchased 4!  The hoodie runs slightly large so I ordered a medium which fits perfectly - body and sleeves.  We have been experiencing a cold snap in the last few weeks and this hoodie has become part of my daily attire.  It seems to adapt to outside and inside temps and keeps me comfortable all day. The fleece outer shell and sherpa lining are very soft and light which makes wearing the hoodie soooo comfy.
