We are proud to bring another hemp product to life, with a new expandable design and a new hemp fabric that is more durable and more waterproof than ever. It starts as a casual 20L everyday bag when fully compressed and it grows up to 45L when fully expanded. The roll-up offers 10 extra liters above and the hidden kangaroo pocket offers 10 extra liters below. You can also attach our front bag in front for an extra 5 liters of space. Weatherproof (PFC free) Durable Hemp Fibers
