In everyday use it holds 25 litres, and an expansion zip takes it to 30 litres. Inside and out there are many organisation compartments, quick-access pockets and hidden stash spots, plus lockable zippers and an RFID-blocking pocket. Padded shoulder straps and a sternum strap keep it comfortable when fully packed, and there is a top carry handle. The outer fabric uses 100% post-consumer recycled plastic and is water-resistant. It measures about 320 x 440 mm with a depth of 170 mm expanding to 245 mm, and weighs 0.86 kg. It is a good fit for travellers who want a single carry-on bag, as well as students and commuters with a larger laptop. Colour: Blue Night, a deep navy, with light taupe zipper accents.
