This rucsac has excellent capacity for travelling as well as a removable, expanding daysac. The Biofit backsystem has been designed by Berghaus for adjusting the back system to give a personal & comfortable fit. There are two grab handles, one on the top & one on the side of the travel bag for easy handling. The shoulder straps can be covered by a zip over cover to ensure that your baggage can travel well, with no need for dropping your bag in the oversized baggage check in at airports.
