“Good visibility, poor ventilation”

“This seemed like a great jacket as I pulled it out of the box and tried it on. The fit is good (very typical fit for me in a large: good fit around the chest, and as usual more room than I need in the abdomen), except the sleeves are shorter than I was hoping. They are too short for me to pull my hands into my sleeves which I do when I run. (My hands always get too warm in gloves until it gets to around 15 F & below.) Also, this jacket does not breathe well at all; certainly not well enough for use as a running jacket/vest as it's name led me to assume. There is what looks like a waterproof breathable layer on the inner face of the jacket (I haven't tested it as the outer Teflon finish beads and repels the water before it ever gets to the inner laminate), but I can't see using the jacket in the rain (other than a light drizzle) as water would simply seep in at the shoulder zippers. This jacket does breathe well enough for light activities, but not for running. On the plus side, the jacket is very well made, and the reflective areas are VERY reflective. It is windproof, as advertised. The pockets are well placed: two abdominal and two chest pockets (one inner on the left, and one outer on the right), all zippered. There is also an elastic drawcord at the waist. On the whole, this is a very nice jacket for casual wear or commuting (on bike), especially at night. However, it is not very useful as a running jacket.”
