Best warmth to weight ratio on the market. Tougher than the Ghost whisperer. Packs so small and is so warm.
I'm 5'9" 151 lbs and I bought the medium. THis has an athletic fit so its still tight and nice looking and not baggy. The small was too narrow in the shoulders and I felt restricted wearing anything more than a tshirt under it.
