“Attachment is easy and fast once you get used to it. Even fully loaded bags can be quickly removed and installed again, e.g. on a train journey. The bags have seen some use but show almost no sign of wear. Very good choice of material! Zippers are running as they should. The bags are not fully waterproof, but can take quite a lot of rain before water seeps in at the seams. I usually pack things that may get wet or pack things in waterproof liner bags, so no problems there. The external nets and sleeves and the loops to lace elastic cord are super useful.”
