Light very breathable layering piece.

Verified Buyer Reviewed by Montanaskiandsail from Montana on Monday, March 14, 2016
Bought this after purchasing a Marmot Alpha pullover jacket, as I was very pleased with how well the insulation worked and provided a more comfortable airy / less clammy feel than regular insulating layers, but still had great wind and light water resistance. (Note this is a very thin, insulated vest, not a puffy / more comparable to heavy fleece.)

It layers well, I bought a Medium, I am 5.10 , 175 lbs. (Would buy a large in the jacket as the shoulders were too tight in medium.)
