The vest is awesomely breathable when running, the mesh back keeps you very insulated. There is good protection from elements with the drop tail providing protection, and more importantly very nice breathability. And of course, there is that sweet overstock.com price on this instead of paying a high number at that running store.

This says it is unisex and it looks wonderful. The design is good, however I purchased an extra large for my husband who normally wears a large and it was way too tight across his shoulders. He said, this must be for women or children, but I tried it on and it didn't fit this women's figure either. I think it is meant for children or undeveloped women. Buy with caution or only if you are tiny. It isn't expensive so it is frustrating to now have to spend money to ship it back.
