For the person that finds a 40L bag a bit too much volume, Polerstuff offers this 20L bag! It will hold 20L of grape soda, wetsuits, or dirty laundry. A great everyday size rolltop for your rainy commute or your trip to the beach. The bag is highly water resistant and features an external accessory pocket as well as a padded laptop sleeve inside. It has a built in zipper so you can buy our dry bag separately and zip it inside and create a two compartment system just like our 40L bag comes with.
