The Kata 3N1-33 is a well-made bag with adjustable straps that can be set up as a backpack, shoulder sling, or a sort of... suitcase, kind of? The main compartment has a multi-opening system that provides access from the left side, the right side, or the front. There’s a second compartment for personal items and a couple of exterior pockets, too, and a large laptop pocket. In good condition, with minor signs of cosmetic wear. Interior dimensions of gear compartment are approximately 16x26x30cm.
