The sweatshirt with a dinosaur pattern may not be of any brand.

The dinosaur on the sweatshirt may be a trademark, or it may be just a print, or it may be just a pattern. It can be used on any clothes.

Coach has several models of clothing with dinosaurs on them. I don’t know if this is what you want. If you are talking about the ones with dinosaur skeletons printed on them, then they are Archaeopteryx.
