I'd suggest you don't get anything except a cable that's tested by Nathan K. and/or Benson Leung. They're two Google engineers who have been testing USB-C cables and chargers in their spare time, and they check whether the stuff complies with the USB-C specs.
Their results are here:

Take anything with rating 1-3 that can carry 100W. I think you can also get the 60W cables as long as you don't charge multiple devices off the notebook.
Your particular taste (black braided) might not be among those rated good. In that case I simply would stick to the tested ones. The problem is that the USB-C specs are currently not well understood by manufacturers. And some manufacturers are trying to cut corners. This can damage your laptop. For instance one of the Google engineers mentioned above got his Chromebook Pixel fried.
