I have written a previous review of a High Sierra Wheeled Duffel model (red) which was more of a canvas type where I mentioned it was punctured and stained on the first trip. This model is made of a different material (synthetic?) and appears to withstand the punishment (first trip) and was not punctured but it did suffer some staining. The bag was big enough for me with a lot of room to spare (expands). It is light weight and easy to roll. I feel it is a huge improvement over the previous model and hopefully it will last me through many more trips.
