Twelve or more plastic bottles are used to make the recycled (rPET) materials that make each bag, and all ROKA bags are vegan friendly too!Each Bantry has four straps for being carried on your back or by your side, with a front pocket closed by a sturdy zip, a secure inside pocket, as well as a laptop or tablet sleeve inside.Made using the rPET sustainable Nylon, the bag has a smooth and glossy feel. It is then coated to make it water-resistant and finally put through a softening process to make it have a softer feel. And our nylon material is weather-resistant, lightweight, and as durable as all our ROKA bags!SmallThe Bantry B small option is the cutest and safest way to keep track of all your daily needs - mobile phone, keys, wallet, and more! Each small bag is 32cm x 23cm x 10cm. Capacity is 7.35 litres.
