On first look the Colossus II doesn't appear to have changed much. It features the same versatile detachable storage configuration (65L rucksack and detachable 15L daypack) but that's where the similarities end. The Colossus II has undergone a complete revamp with better components and materials used throughout but most importantly for intrepid travellers, this new version has an improved backsystem and a kangeroo attachment for thedaypack, perfect for hostel hopping or sightseeing around town.
