I bought this for walking at night, but I love it for running errands. It is light weight, but warm. The lining is really soft, feels like fleece. I am 5', and the sleeves are very long for me. Would be perfect length if it had thumb holes. I have to roll them up. Besides the sleeves, this is a very comfortable and flattering jacket. Definitely recommend. Wish it came in more fun colors and with a hood.
A colleague said this was her favorite jacket for running all winter in New England. It's lightweight, breathable, warm, and reflective--and gives the wearer a beautiful silhouette. I bought the S for my daughter who said it was "perfect" and returned the other jacket she had purchased. I'll definitely return to illumiNITE when shopping for similar items.
