The quality of the bag is good. However, the zip is difficult to manage. The nano pump does not work very well in inflating the bag. So I struggled each time to remove the contents as it was almost impossible to unzip when the bag is in a deflated form. It was quite frustrating when you need to remove the content from the bag urgently. It was also difficult to remove the nozzle from the pump in order to inflate and deflate the bag.
