Good first impression. Was very comfortable in this jersey with a second jersey underneath in cool, damp weather with temperatures just under 50 degrees F and falling. I would characterize this as a medium weight jersey. It's heavier than basic lycra/spandex, but I have had several thicker fleece or heavy thermal jerseys for colder temperatures. This will be more versatile in the fall/spring but will require extra layers for the next 2 months.
One word about color: the green is a much "truer" green and not the turquoise that shows up on the website.
