Sea to Summit Sling Bag. Please check the size as it is shown in the photos. The bag has a zippered flap. The last photo shows the zipper fully closed. It's very well-made. It packs down incredibly small when stored in the included carabiner-attached case made of the same fabric, and can be attached to a bag. This item is unused and has been stored without a bag. Please refrain from purchasing if you are looking for a perfect item. Due to shipping costs, the item will be shipped without the small bag.
