ARVA BACKPACKS RIDE 30+ BLACK

Thanks to its roll top opening, you can go from 30 litres to 38 litres just by unfolding the bag.  There's plenty of storage space to keep your gear organised during your raids: two small quick-access pockets, a security pocket and a pocket on the waist belt. All this in addition to the central compartment accessible via the rolltop opening or the back opening.
