I'd need to see a picture of the tag and close ups of the zippers. Those zippers don't look like any of the ones I have or have seen. That O looks wrong too. The drawstrings don't look right either.
My all time favorite hoodie has a logo similar to this but much bigger. Where the original material is cut and the back piece sewn in behind it. The zipper as mentioned looks wrong. Hard to tell with just one pic and no details. Bottom Left
With as much fake stuff that comes out of Brazil who knows. Some of the tag info does add up. W07 = Winter 07 release. The part number looks consistent with other clothing releases and the BR could designate a Brazil only release.
