I have had this bag including the 2 larger ones (I bought it as a set) for about 2 years now.  I have been on many trips including car, plane, and train and it is still in perfect shape.  To those complaining of space the company clearly suggests this for a 1-2 day trip.  I have used this for up to a 4 day trip and I am not a light packer by any means.  I would definitely buy this again!!
