Replying to SMS Puffer - is this puffy quality/warm?

So is this jacket, http://www.smsclothing.com/website08/index.php?option=com_content&task=view&id=16&Itemid=43
warm and quality? I live in a really cold part of alaska and quite frequently ski -20F temperatures, so it needs to be warm/quality. Since the searchbar didn't help and there are no review on it, I was hoping someone could help me out here. I've also heard that SMS didn't make a legit product, but can someone set that straight too? thanks

++karma for any help
