Authenticity of unknown North Face hoodie name?

I purchased a North Face boys fleece hoodie today from Plato's Closet. I bought it on a whim as it was only $18 and I have found authentic items there at great prices. I compared it with the girls Khumbu fleece jacket I purchased at 's Sporting Goods this past winter. The fleece on the unknown one is considerably thinner. I also looked at the logo. There are no lines connecting the letters like a lot of the fake ones have. The font also seems to be correct. There are no stray threads, except for one or two on the inner pockets. The rest of the stitching on the inside is tight and even. The outer pockets are angled similar to those on my Khumbu jacket but these ones do not have a zipper. There are three white inner neck tags, a smaller one that has the North Face logo and says boys/garcons with the size in a rectangular box below it. It also says where it was made. The next tag says it is 100% polyester and the third has the care instructions on the back. A black YKK zipper was used for the main zipper. Do you think it is authentic? Thank you so much in advance!
