The Ramverk Alu Carry-on is the first aluminium luggage from Db, the Norwegian brand that built its name on ski and travel bags for people who move with equipment. It is sized at 55 by 40 by 23 centimetres to fit standard overhead lockers, and it is built around two named structures: a CenterFrame spine in 6061-T5 aluminium that distributes load and adds torsional rigidity, and an EdgeFrame in 5052-H32 along the outer edges that absorbs and redirects impact. It made the cut for a reason the luggage industry rarely offers, which is repairability as a design principle rather than a warranty promise. The construction is rivet-free, and the brand counts 369 individually replaceable components, with parts changeable at home using a Philips screwdriver and a hex key. Wheels are Japanese Hinomoto 360-degree units in custom housings, the trolley handle is a one-piece aluminium telescopic design made for the case, locks are TSA approved numerical units, and Db Black membership carries a ten-year warranty. That approach matters because aluminium cases usually fail at the hardware long before the shell gives up, and a case you can strip and rebuild extends its working life in a way a sealed rival cannot match. List price on Db's own store is NOK 8,999. Verdict: Expensive, heavy in spirit if not in hand, and the most honestly engineered aluminium carry-on currently on offer.
