The North Face Prolix Vest - Women's - 2009 BCS

This is a very thin vest, as in the description. Despite its thin-ness, it seems to provide a little bit of warmth. I bought this to wear as an outside layer while running in windy/light rain conditions. I wore it on a run the other day in 20mph winds, and it definitely made the weather more tolerable. I like that it's not too thick, because I don't like to be too warm when I run; the vent in the back is nice for this too. I like that both the front chest and back collar logos are reflective, for when I run in lower-visibility conditions. A note on sizing: I first ordered the Small, as I have a 35-36" chest and 26" waist, however I found it to be very baggy, and almost too much room in the armholes. I then ordered the XS which I find to fit much better - it is slimmer fitting, yet still plenty loose enough to wear over a long sleeve shirt. There's even enough room to wear it over my TNF TKA100-weight fleece (I'm not sure I'd want to though). A note on the color: I was expecting a light navy, but found it to be more blue in real life. Also, I couldn't see this in the pictures, but on the blue ribbon vest, the mesh inserts at the side are light blue, like the inside of the collar. I wasn't a huge fan of the blue myself, so when I ordered the XS I got it in black.
