Ran with this for the first time this morning during a 26* run. Long sleeve shirt underneath, and I was more than comfortable. I will use this daily for the next 5 months. It's super stretchy through the sleeves to accommodate layers without being baggy. Also, as someone with ample hips, I often worry about the fit of these kinds of things, as staying down and having it zipped can be a challenge. Not so with this jacket. I really can't recommend it enough.
