Great weight - great length

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: large

Perfect midlayer - love how it's a little longer, so it sits just below the hips - this is nice for a little extra warmth and also just looks good. The sleeves are a great length as well. I ordered a large and it fits as expected - in fact, better than expected - I wanted it fitted, but not skin tight and it's not. LOVE IT!
