Notice the description says it's a sweatshirt, not a sweater. So I guess the difference is that sweatshirts are thinner.
Cool looking though, when I first put it on I felt like some sort of ninja ready to go in the dark and take over the bad guys. Yeah it's that cool.
One of the things that they don't put in the description is the fact that this sweatshirt is water resistant, meaning that whenever you put water on it, it will slip right off. So this hoodie is perfect for those rainy places, but not so much for those colder places.
The added thumbholes are a big plus. It looks really cool when you put your thumbs in there.
My only complaint is the actual zipper. Whenever I try to zip it up, I have a hard time doing it and the zipper feels hard, not smooth. This is weird coming from Oakley. Even my non-brand hoodies have better zippers. Not a big deal though, I can live with that.
