Very warm and comfy

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

Really nothing to say about, which is the highest compliment IMO..
Slept in 35F with only this on and my 20F quilt, IDK which is warmer. This plus a nice fleece helped me hiking in sub-freeze environment easily.
