Some people don't like Levi's (I am SHOCKED!) and they prefer Wrangler, instead. While they are also nice, the also have the comfort that Levi's have, practically similar but it's the style where if one looks closely, you can tell the difference.
Some people just like 'different' and that's ok. With Wrangler you get a better price sometimes. The only thing is not as many colors.
Also being a worldwide favorite, you might want to see what is available for you. Click here! and the do ship INTERNATIONALLY which is good.
