that necessarily bad?
http://en.wikipedia.org/wiki/Fake_fur* Fake fur is not as warm or insulating as real fur.
* Fake fur is not a natural material, therefore the wearer's skin cannot breathe like it would in real fur or leather.
* Fake furs are not able to keep snow from melting and re-freezing on the fiber filaments; this is very important, especially in hiking, mountain climbing, skiing and other outdoor activities which are done in extreme conditions.
Basically, it's not as warm as it looks, it won't breathe well (you'll be warmer in warm weather, and colder in cold weather), and is, more or less, decorative. If I were going to wear it, I'd wear it as a spring/fall jacket, when the weather is more mild. Normally, I don't know diddly about fashion / clothing / etc, but I've seen the faux fur discussion with viking/barbarian/early period soft kit for camping events, so this was just coincidence.
Now, that covers the jacket. The 0 reviews is a little odd, since I usually like to see some feedback from other buyers before spending money on it. It's not a game stopper, but it does make me pause for a minute to think.
But, hey, $15? Take a shot, as was said, if you only get a few months use, you're still ahead.
