Review: Deuter Up Seoul 16+10L Backpack - YouTube。From the Deuter website: It has all the functionality you want in an urban pack but is produced in a resource-efficient way, so you can make your commute with a clear conscience. This is primarily because the UP Seoul is made entirely from recycled materials 37x 0.5-litre PET bottles to be precise. The textile manufacturing process is carried out according to the stringent bluesign standard. And secondly, the amount of water and crude oil used is significantly reduced. The UP Seoul is designed to accommodate everything you need for a day at work, at uni or when youre just out and about. With its new wide aperture fold-over zip closure, you can even expand the capacity by up to 10 litres. This style of opening also provides good oversight and quick access to contents within the main compartment. Weight: 1.85 lbs Volume: 16 + 10 liters Dimensions: 19 / 12 / 5.9 (h x w x d) in Recommended load: 6.61 - 13 lb In excellent used condition. Has been hand washed once before selling.
