Disclaimer. This jacket was a gift. I’m suspicious as to authenticity. Here’s what I know. Fully seem sealed and the tape and glue look legit GORE-TEX Pro material YKK Zippers Feels legit Bright blue color Seems (sewn seems) look good Why I’m suspicious: The label on the inside and the coat hanging loop No tags Jacket has never seen snow or rain. It’s too big for me. But I tested water on it and it is for sure water proof. If you’re looking at this, it’s a gore Tex jacket with all the tech, and possibly the brand, but we can’t know for sure. I’ve always thought this was could be a sample run or some other demo version. Very nice jacket though.
