The original collection was designed from industrial wool felt.
Honoring the craftsmanship of argentinean tanneries, a vegetable dyed 'all-leather' version soon followed. The ØW Collection (Zero Wastage) was added in 2010, bringing a new angle to the 'sustainability' agenda. Recently, a sleeve collection for Apple products was launched. In the Felt and the Leather Collections, the main body of each bag is made from a single piece of material that, rather than being sewn, is assembled using aluminium rivets. The bags in the ØW Collection are made from single strips of material cut from side to side of a roll, without any further trimming. The Carga collection is batch-produced in a family-run workshop in Buenos Aires, Argentina. Each bag carries an metal disc embossed with its own serial number.
