It's hard to say for sure but I know I've looked on the authentic marmot website for a Greenland baffled and after seeing this website I noticed that the photos they've used are taken straight from the marmot website which raises a red flag for me since most companies have their own models to model the products they sell instead of using other website's photos. Now add to that the fact that each and every site I've checked are selling the coat for $449.99 but this site has it for $147.00. Over $300 difference! Unheard of with authentic ANYTHING. I won't be gambling my money on their items. I'd advise you not to as well.
