The magnesium bag is qualitatively worked very well. I have read two reviews, which I absolutely disagree, because holding the bag, what one expects / what you erwaret. Firstly, it's just a climbing tool, so you should not make much hiking backpack when buying expected (I have actually read so). On the other hand leaves the bag also wonderfully close and re-open, I have no problems with the train system. Perhaps Edelrid revised this train system, or the other review is from a defective product ... Nobody Knows ... All in all a product that I would weiterhempfelen good conscience.
