How would you describe this jeans style?

Check out these jeans: a href="http://us.levi.com/product/index.jsp?productId=10911925" rel="nofollow"http://us.levi.com/product/index.jsp?pro…/a Levi's calls them jeans, but would jeggings, leggings, or even tights be a better description? What would you call them if you didn't know they're sold as jeans?
