I got the Terry bolero light. They also make one that is heavier weight with a more fleecy lining. TE carries that one as well as some boleros by other manufacturers. The bolero light ran small and pulled across my upper back when I wore it. I wear a size small in every top I have, but I had to send the small/med bolero back and get a Large/XL size, which fits with plenty of room under it for even a long sleeved jersey for an extra layer.
