The Patagonia Terravia 3L Sacoche Bag is a pouch pocket for hanging onto your valuables. Leave your shorts or pants pockets free and light and tuck keys, snacks, and phone into this little bag instead. The front stretch mesh pockets provide quicker access to items you need more often, while the zippered main pocket adds security for items you prefer to keep safe. The shoulder strap is removable, allowing you to strap the pocket to a larger pack or use it as a packing cube.
