Whoever designed this is genius. At first, I thought it was a little overpriced for what looked like a large shopping bag that you can typically buy for $5 at a grocery store, but not only is it huge, but it's got this slip for traveling with a suitcase (see stock photo for what I'm talking about). I carried it around for a week during a trip and it was pretty sturdy and durable. Obviously not meant for heavy duty use, but it was perfect. It made it so much easier to walk with a suitcase, because you don't have to worry about it falling off.
