I love this jersey. First of all, I have lots of Windstopper stuff - another l/s jersey and a couple of vests and baselayers etc.. The C7 Windstopper jersey is different. It is much more effective in keeping out cold wind. When I started a three-hour ride today it was in the mid-50s with a cold biting wind out of the northwest. I was fine with just this jersey and a WS vest. In fact, in about 15 minutes, the vest had to come off. By mid-afternoon, the temp had climbed a bit and we had a bright sun. When I ordered this jersey, I wondered how easy it was going to be to get the sleeves off. It was no problem. I was able to unzip the sleeves with no issues. (this is my first zip-off product). I didn't have much use for it before, but now I think it is a nice feature. This is a complex piece of clothing with all the panels, the sleeve inside of sleeve and all the zippers (seven!!), so it is understandable why it is expensive. Sure glad I got 25% off. One other thing. These folks are lightning fast in fulfilling orders. I got my order confirmation email and 27 minutes later I got my shipment confirmation email. Amazon, eat your heart out.
