the fleece material appears sturdy & packed with warmth and unexpected thickness.  the overall fit for this medium size I have is quite suitable for my need.  if this is for a inner layer, it would be make you toasty undery an outer layer under some circumstances. for the price, this is very recommendable. It might not be the same quality as a REI woodland model which cost nearly $40, but economically, this is second to none. My four stars is due to the fact that the zipper is not yet "REI" quality and that the fleece is rather hairy
