I bought this running jacket to wear in cold weather and am very happy with it. This 1/2 zip is more like an "Under Armor" shirt as it is very snug. I was a little uncomfortable at first but once outside it gave me all the warmth I needed. I later discovered that it has thumb holes, which were pretty good. It does exactly what I asked for. Pros: Comfortable, very warm thumbholes. Cons: a little cramped.
