I know these bags are more expensive, but honestly, they are the best ones out there!  They are sturdier, less sheer, and really do mask smell better than other poop bags I've used!  Poop bags that are scented (which Mutt Mitts are not!) really add an extra awful odor to the poop and just make the whole process worse!  Mutt Mitts are the way to go! :)
