In general, I am satisfied with the product during its use on day hikes. Unfortunately, Salomon offers it in sizes of 10L, 20L, and 30L. I would like it to be slightly bigger, for example, 35 liters. On the positive side, the backpack is lightweight, of very good quality construction, and has excellent shoulder straps. On the negative side, I would say that the pocket with the stopper for holding a 2L water bladder cannot hold it. It has no problem with smaller ones. Also, the side mesh pockets are somewhat loose and cannot hold small bottles or half-liter water bottles (there is no problem with larger ones)
