I purchased this jacket in October and have worn it on about 10 rides. I have used it between 32F and 57F. On the cooler rides I wore a long sleeve under armor rush base layer. On the warmer rides a short sleeve layer of the same kind. The jacket is completely windproof and breathable. After a little more than an hour of riding I am still warm. At the end of ride the base layer and jacket are damp with sweat without compromising warmth. The zipper on this jacket is excellent and works easily with one hand. I love the fact that it has 3 pockets onthe back like a cycling jersey. I do not like jackets with zippered rear pockets. Then bright color is excellent and when i wash it i usually check for spots and use spot cleaner. I ha worn this jacket on several night rides. It could use more reflective surface area. The price on this jacket has gone up about $50 since October. That being said, i would purchase another at the higher price.
