The Terravia Sacoche from Patagonia is an infinitely useful pack for organising essentials on metropolitan excursions and laid-back hikes. Constructed from quick-drying recycled nylon ripstop, the bag promises years of service, and is equipped with 3 litres of carry capacity in its main compartment. Bolstering storage is an internal zipped pocket (of which the style can be packed into when not in use) and two external drop-in mesh pockets for easy access to all your necessaries.
