Depends on what you're using to layer underneath. I tried it for the first time in 40+ degrees, high wind, and setting sun with a heavy sweater underneath and it performed like a champ, which I did not expect. That said, I would not hesitate to use it in temperatures up to 60...again, depending upon your base layer.
