In this usage, the term “ultimate” does not refer to mix martial artist Caol Uno‘s fight venue, the Ultimate Fighting Championship, but to the clever design by PORTER‘s creative team. From the onset, the collaborative day pack appears to be like any of its peers. However, an integrated storage system and hidden compartments mean users could store away all the essential gears for a day trip. Additional pockets on shoulder straps allow quick access to modern necessities, like cellphone or digital camera, without sling the bag over one shoulder only. With 3-layer construction with seamless zippers, the Ultimate Multi Storage Day Pack is the ideal accessory for any short trip. Part of the UCS Fall/Winter 2010 Collection, the item comes in light grey or black. Scheduled to launch in mid October, however, interested buyers could place a pre-order, from now till July 12th, through Cueve of ZOZOTOWN.
