It seems almost every day brings a new Porter luggage collaboration… and this is no bad thing, as their dedication to high quality, functional baggage rarely disappoints.  Here we have their latest collaboration with Caol Uno’s UCS in their Ultimate Climbing Backpack.  This super adaptable rucksack can not only be easily converted to a tote, it also comes with a range of compartments, outdoors details, detachable pouch system, and superb mountaineering craftsmanship.  It comes in both khaki and black and is available from UCS now.
