Inspect the seams, hanging strap, buckle, outlet and tube. Check for damage and leaks before you leave.
Choose a stable hanging arrangement that follows the bag’s instructions. Keep the bag and tube away from sharp surfaces and dirty drinking outlets.
For treatment, confirm a compatible separate filter, the required connectors and an appropriate receiving container. A straw or mixed set does not establish compatibility.
